I want to turn on/off an LED light from my bluetooth enabled mobile (iphone) phone

 I've heard about Arduino however the circuit board is very large, is there something smaller I could use instead or another method. i've seen this video about a bluetooth mini car would it be possible the make the LED device as small as that? http://www.youtube.com/watch?v=9Wd4nt_d2Ig

If someone could point me the right direction i would greatly appreciate it!

Thanks

I just saw this on Hackaday. The guy hacks the small bluetooth part of a cheap pair of headphones to make a bluetooth controlled switch.

Might be what you're looking for.
