Dimmer control circuit

I want to create a dimmer circuit. ie the Arduino controls the intensity of a standard AC bulb over time. The method of control (PWM vs DAC) will depend on the hardware circuit, and the light should not flicker. I was almost thinking of buying a rotary dimmer switch and attaching a servo to it but I figured there had to be a better way. Any ideas?


look at this: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1160909656/4#4

and if not, then go for DMX. search this forum, you will find more info.
