Just a bit of fun for Christmas. Easy to make, and quite effective in dim light. (The red letters show up better than the green ones, and there is almost no difference between the red and he orange!)
Unfortunately, the video does not film flashing LEDs very well, because of the shutter speed, but the still at the end shows what you actually see. (Inspired by the Picaxe project No.135). of course it can be programmed to display any text you can dream up.
