The LED rainbow table has some competition in this Peggy 2

Remember that really colorful LED table we saw yesterday? Well, it may be out of a job — that is, if it ever had one. The Peggy 2, when loaded and programmed correctly (Arduino, of course) seems to do what the rainbow table does, but with a slightly higher resolution, and narration. The granularity of the 2×2 aggregate “pixels” is pretty distracting until you see it with the diffusion sheet over it. Of course, that means your sprites (if you can fit any on there) are going to look like soap opera stars in a flashback dream sequence.
