This is what I've been doing for the past 3 months. 9-foot tall tetris in the front yard. It is run on an arduino and is controlled by a playstation 2 controller. Each led is gently stuffed into a ping-pong ball and glued in place. The leds are held in place by a grid of network cables(world wide web, amirite?) which are tied to a rigid PVC pipe frame.
Satan4.0 had some trouble which brought down randomosity 2 weeks ago. But we could rebuild him, we had the technology, so say hello to Satan4.1
Satan4.1 boasts a raid array to prevent data loss, backed up onto a removable backup drive. The new system is also behind a firewall which for now seems estonia-proof.
This seemed a little boring for a comic, so I made it into a tee shirt instead. There will also be a wall poster of this design.
On an unrelated note, I be having a few shirts made in bulk sometime in the near future. Post in the comments thread if you would be interested in having a standard Randomosity shirt for just over $15. I need at least 12 people to make this work.
