This just screams disaster waiting to happen. Someone could lose an arm.
Heck, if you have to consider this at all, it means your ceiling is so low that someone could stand up into it. Broken mirror, shards of glass in proximity to head and neck...
I got squeamish just looking at the pictures of that mirror under the table. I couldn't sit under a mirror stuck on the ceiling; I wouldn't reach under a mirror stuck under the ceiling... no way, no how.
I have a lot of concerns about mirrors as well and for the same reason as you do as well as a few others.
Whenever you interpose a reflective surface between your projected light image and the image you ultimately look at - you get light loss and your image contrast can flatten and optically distort. We are not talking about controlled optics - we are talking about spit and kleenex construction here. So...it concerns me.
But, depending on the set-up and projected image, light loss can be more theoretical than real to the eye.
While a heavy glass mirror seems an epic disaster waiting to happen Wulf (and I am in total agreement with you on this point), there
is more than one way to skin that cat. Mylar is the most reflective surface known to man. And it is exceedingly thin, non-breakable (in the bad-luck, catastrophic to health sense) and - above all - low in weight. [Hydroponic grow-shop as gaming supply store: who knew?]
There may well be a way to incorporate mirrors that make sense, aid a set-up and address a real and pressing need in digital map projection. Show me pics and after battle reports of a great mirror set-up and I am very interested in listening to the whys and hows.
I tend to be skeptical about adding needless complexity to things, however, and over-engineering is iconically geeky. To add a mirror to genuinely improve matters is fine; to add one just to add one or make a tolerably large image a wee bigger is less convincing to me.
