New Invocations for Warlocks

[DungeonmasterCal]

I was reading the BoVD last night and while adding Empowered Spell Like Ability and Quickened Spell Like Ability to the list of feats available for the Warlock in my current campaign, it occurred to me that someone somewhere must have some new invocations for a Warlock's player to choose from. Is there a thread for new Warlock invocations already existant? If not, has anyone created new ones you'd like to share?

I worked on a disguise self like invocation a while back, alowing warlocks to take on the role of a doppleganger, I think we ended with 3 seperate versions. I dont have search to find it though.
