Clap on. Clap off. Watching old TV shows, we remembered that old advertisement and a light bulb clapped on in our heads. With lots of time on our hands over the weekend, we put a simple clapper together to turn the lights on and off. Then we thought, it’d be pretty cool to have some dancing lights when we play music . . . so we wrote a quick program to make the some Christmas lights dance while we played music. Watch the video below, and check out the dSwitch page for the program and more information! Special thanks to Brian Davis who led us to this idea!
