I'm working on turning it into a IR emitter to control some stuff that I have that lack remotes. I have another I've loaded snips onto an will be experimenting with soon - I'm currently using a PlayStation eye for the experimentation, but will have to get a better microphone/speaker. I wish I could hack a dot/echo/etc. and use their microphone/speaker, but meh, I'll take what I can get.
Also, the IR pi will probably drive some ambient light as well.
