Alright, one last holiday hack before we surface out the year. Every Christmas Eve [ryan rose]’s household has a contest with a new theme. The difficulty this year was to build a Christmas wreath. Ryan made a decision to make a Simon Christmas wreath. He cut up a string of lights to create the four separate color regions. He triggered the lights utilizing an opti-isolator circuit as well as developed buttons that look like presents. You can view his building pictures at Flickr as well as enjoy a video of it in action at YouTube.
