CHECK this out!  Beonhome.com    This KickStarter project was funded in December.  I love this idea.  The lightbulbs “learn your lighting patterns” and can replay them if you are away from the house.  They can come on with certain sounds – like a doorbell.  They can play a sound in reaction to the doorbell.  They slowly fade after you turn them off so you can still have lighting for brief period.  That could give you some time to cross an otherwise darkened room.  You can even control them with your cell phone.  There are so many great applications for these bulbs but of course I think of the ways this would make many of my patients safer in their homes.  Can you think of other applications?
