Okay, this isn't a clock but I think you're going to like this. Josiah emailed me to submit a few of his creations to the site. I've broken his submission in to several posts and this is the first. It is a sculpture based on:
All of this is supported by an acrylic column that has a right blue and green LED illuminating the center. He achieves a smooth fading effect by using PWM to smoothly transition between the colors. This thing just looks amazing. As far as the motivation to build all of this? He states: "The result of about a week of work after a friend asked me to build an interesting lamp for his art installation at the Coachella Music Festival." Mission accomplished!
I am not going to steal all of his content and publish it here so be sure to stop by his site for more information, photos, and schematics.
