Controlling 220v Bulb using Raspberry Pi

I have always had this excitement to control high-voltage devices from electronics. I could never do one because of lack of hardware and/or the scare for dealing with high voltage and getting it right the first time. Finally, I now have a proof of concept project that controls a 220v bulb from a Raspberry Pi. More details, maybe in a later post. Right now, I need to build a better actual project with this :) 

Raspberry Pi runs on Raspbian Wheezy linux and the controlling code is written in Python.
