How about hooking up a Raspberry Pi to an X10 master so you can turn you lights on and off and then hook it up to the internet so you can turn lights on and off remotely. I don't believe you've done anything X10 based yet, so that would be new. Maybe have some programmable randomness so the lights can go on and off with in a period of 1 to 2 hours, but randomly in that time frame.
