The system here uses some cheap remote controlled outlets, some transistors, breadboards, and the Raspberry Pi to power a system where you can remotely turn off a lamp from anywhere. It's not just a lamp either, you can turn anything connected to the outlet on and off from the internet. The build requires some soldering, but if you're interested in building something like a DIY WeMo for yourself, Minardi's build is a good place to start.
