First introduced in Japan and then the United States 1984, shape memory polymers are polymers whose qualities have been altered to give them dynamic shape "memory" properties. Using thermal stimuli, shape memory polymers can exhibit a radical change from a rigid polymer to a very elastic state, then return back to a rigid state again.

Modern variations on the classic turn-of-the millennium shape memory polymers react to other stimuli than heat.

By the late 2020’s, SMP characteristics can be engineered into almost all polymers, allowing for automobile fenders to be bent back into shape with the application of the right amount of heat; the creation of multiform solid-state furniture that shifts to accommodate different users with the press of a button; and a million other household uses. Some low-rent apartment buildings even use piezo-activated SMPs for the doors on their units so the door can be quickly ‘melted’ with the application of a simple stun-gun-like device.

This short PDF presents over 20 different pieces of Progress Level 6+ equipment, weaponry, armor and day-to-day items that have been made possible due to the 21st Century miracle of shape memory polymers. From knives that change form once inside the victim to new state-of-the-art skateboarding gear.

Shape Memory Polymers is a 10 page PDF detailing the origins, uses and game effects of an interesting area of near future tech. A little different from most equipment guides in that it looks at a single bleeding edge technology and extrapolates what uses it could be put towards a few years from now. The PDF could easily slip into the pages of the better cyberpunk-genre gear books out there.

First Impressions

This is only the fourth PDF I've looked at from EN Publishing however it maintains the same high quality of writing and graphical presentation I've seen in previous works. The writer gives a simple layman's explanation of the subject littered with several examples of the technology.

Fluff

Shape Memory Polymers are in essence plastics that can change between two forms when given the required stimulus (heat, electricity, blunt force, etc...). The PDF gives lots of ideas on what the stuff can be used for in mundane life. This is what really hooks you with this product because it plants seeds for your own ideas on what you can do with SM Polymers. Even the crunch material has great story backup and uses fictional corporate branding to accent the presentation of the game mechanics. All in all, a very easy to read and interesting supplement.

Crunch

Shape Memory Polymers gives lots of gaming goodness for those looking for new material for their D20 Modern/Future games. Body armor, guns, and ballistics are the areas that will be of most interest to players. I know several gun nuts in my own group will find what amounts to armor piercing dum-dum rounds appealing. The rules do a good job of balancing real world effects and game mechanics. One thing I did notice, particularly with the armors, is that there is some additional bookkeeping. Certain equipment has modifiers which change on a round to round basis as it moves from one form to another. Not an excessive amount of extra accounting but it is still there. If you're used to calculating varying spell effect modifiers during your D&D game this should be a snap.

Conclusion

BlackHammer Tech - Shape Memory Polymers is a good little supplement for someone looking for something new to add to their d20 Modern/Future game based off of real world science. It is an easy and interesting read. It's only short coming is just that, it's short. You really want to see more toys that use this neat material. On the flip side it certainly got my mind working on some neat things I could do with it. And for the price the inspiration is gives comes cheap.
 

Thanks for the great review. Not only am I the publisher, I'm the author.

As for the good ideas you get from reading this, I'm in the process of putting together volume two of this book, and any new material you would like to add would be much appreciated.

New Tribes – Shape Memory Polymers
E.N. Publishing
Author: M Jason Parent
Page count: 8 + Cover + OGL
Price: $2.00

This new product from E.N. Publishing describes a new technology for near future d20 games. This technology is shape-memory polymers (SMPs); plastics that change form under the proper stimuli – an electric charge, heat, impact, and so forth. The concept and technology are interesting, but New Tribes – Shape Memory Polymers (NTSMP) falls short of fleshing out the ideas.

NTSMP begins with a brief introduction, explaining shape-memory polymers from the origin to the near future. This is an actual technology that is in its early stages.

Following the introduction is a section that provides some common uses of the SMPs in the near future, including tires, electronics, and pants. Yes, pants. Lightweight plastic pants that are oversized. The wearer hits a button that generates an electric charge in the pants. The pants then shrink, becoming skintight. I find the concept lame, yet having observed numerous fashions, painfully believable. When the technology actually becomes practical, I can easily imagine these being quite the fad.

General equipment follows the common uses. This section is quite brief, detailing only a few items. These items include SMP rope and grapnels. These are not particularly interesting, but have just enough of a future twist to fit in cyberpunk style games.

Weapons. When dealing with shape-changing plastics, you have to expect a selection of weapons, and it is next. As with the general equipment section, NTSMP details only a few SMP weapons. These include the spineblade, a knife that sprouts spikes, making for a nasty effect. Also included are cesti-like gloves that harden on impact, increasing the wielder's damage.

The ideas behind these weapons are interesting, but the mechanics are questionable. Take the spineblade for example. The basic effect to represent the increased damage is an improved critical multiplier. However, in addition to an increased multiplier, the spineblade has a special effect. If the wielder succeeds on a Strength check with a successful critical hit, the critical multiplier increases by one more. This represents the wielder withdrawing the now-spiky weapon. I'm wary of mechanics such as this in games with an abstract hit point system, as found in many d20 games. In most d20 games, hit points represent a combination of factors that include, but are not limited to, actual physical damage. In d20 Modern, the low massive damage threshold refines this concept. When an attack forces a massive damage save, the attack involves actual physical damage. Thus, for a d20 Modern game, a more appropriate mechanic might involve increasing the DC when the weapon attack forces a massive damage saving throw.

After the weapons comes armor. SMP armors work on a principle similar to that of the gloves mentioned above. When struck, the armor alters form in order to redistribute the energy of the attack. While the game mechanics are solid, the idea seems more advanced than the technology implied in NTSMP. I'm not a physicist, but I would think that by the time the bullet hits you (or, in case of the gloves, you hit the target), the damage would already be inflicted, before the armor could respond. As written, the SMPs seem almost prescient. Of course, semi-aware shape-changing plastics are an interesting idea.

The armor section also includes SMP gear for skaters. Because, you know, in the future, skaters rule. Actually, I've always wondered at the omnipresence of skaters in cyberpunk settings. Is it an artifact of the time when cyberpunk games were more popular? Personally, when I think of skating and the future, I'm reminded of Highlander 2 and the hover board things. Then I'm saddened because something reminded me of Highlander 2. Anyway, the skater gear is neat, even if they do actually use the "S K 8" abbreviation.

NTSMP ends with descriptions of two SMP ammunition variants. Other than being SMPs, these aren't particularly different from the non-SMP variants. This section needs notes on how these ammo variants interact with the increasingly common Armor as Damage Reduction rules. While not a core rule, Armor as DR is out there as OGC and, I believe, common enough to warrant a mention.

Layout and Style
New Tribes – Shape Memory Polymers uses a standard two-column layout with an easy-to-read font. The heading font (Metrolox, I believe) is distracting, but the blue color helps it to stand out. NTSMP's look is appealing – white and metallic grey, with light grey grid lines. It's clean, slightly sterile, and futuristic. The tables are clear and easy to read. Overall, NTSMP is an attractive document, though it needs a more efficient use of the space – some of it is simply wasted.

Art
New Tribes – Shape Memory Polymers contains five pieces of art, plus the cover. The art simply depicts some of the products available in the document. The images are set on light grey grids. The art is clean and clearly shows the products. I like it; it reminds me of Fields of Fire, and the Street Samurai Catalog from Shadowrun. I appreciate functional art in game products, and this art is functional.

Open Gaming
According to the Open Game Content declaration, "All text in this volume except for all E.N. Publishing logos, trademarks, product names and product lines is released as Open Game Content." I find the inclusion of product names and product lines as protected content interesting. I can see some value in protecting the fictional company name "Carnivore, Inc." (A weapons manufacturer it seems), but I don't see much need to declare "Quick Release Memory Grapnel" or "Frangible Plastic Munitions" as protected content. However, this might be my personal bias – too often, people often declare unusual and unnecessary things as protected content.

File Utility
New Tribes – Shape Memory Polymers is unlocked, allowing copy & paste, page extraction, and image copying. I appreciate those who make unlocked documents – such documents are far more useful that locked files. Unlocked documents save a tremendous amount of time when making handouts and small docs for games. In addition to being unlocked, NTSMP has complete bookmarks. Even if they are just a few pages, pdfs should always have bookmarks. It is a good habit for creators to have.

Conclusion
Like nanotechnology, SMPs are interesting, with amazing game potential. Unfortunately, New Tribes – Shape Memory Polymers doesn't even begin to scratch the surface of possibilities. Reading NTSMP is like reading the first couple pages of a sourcebook, and then finding the rest of the book empty. NTSMP opens a fascinating door, but fails to step through.

I'm giving this 3 stars - average, because it isn't so bad as to earn only two stars, but there isn't a 2.5 star rating.

"Product names" and "product lines" in this context refers to EN Publishing's product names and product lines. In other words, the product name "Blackhammer Tech - Shape Memory Polymers" and the product line "New Tribes". It does not refer to the names of fictional "products" described in the text. "Company names" refers to the publisher, "E.N. Publishing".

It's a standard OGC declaration - we release everything as 100% OGC except for the names of the book in question, the name of the company producing it, etc.
 

After the weapons comes armor. SMP armors work on a principle similar to that of the gloves mentioned above. When struck, the armor alters form in order to redistribute the energy of the attack.

As written, the SMPs seem almost prescient. Of course, semi-aware shape-changing plastics are an interesting idea.

FYI this isn't all that fantastical even today. Research is being conducted today on what is called "shear-thickening fluid armor". When hit by sufficient kinetic impact the particles in suspension interlock and the round is now striking (semi-) rigid armor and thus reducing blunt trauma.

There is the developers' homepage here. One can also look at the article in The Free Republic, or on SoldierTech.
