yer_averagejoe said:heard of this kind of thing before it can be used with an X10 home automation system but i understand you're point, its just not exciting enough!
At the dundee college of art this year I went to an exhebition where you could text a computer and it would display your message. it was actually called a "feelings board". you'd text something that would go after "i feel" and it would put up "i feel...*whatever*" it was pretty fun!
Another thing on display was a bench with an LED readout with the same purpose. There were pretty funny videos of the benge being tested in public.
Yeah ive actually done the LED thing... just sending messages to myself makes me feel wrong!
