Flip Dot Display Visualizer

Posted by Al Sweigart in misc   

Similar to my scroll art concept, this Flip Dot Display visualizer tool mimics the flip dot displays you see on buses and other large signs. The tool can be fed a list of [x, y, pause] triplets detailing which dot to toggle and how long of a pause to employ after the flip. The idea beind this tool is that beginner programmers can write programs that generate the animation sequences for interesting binary bitmap artwork. There's over 50 demo transitions (where each dot is flipped exactly once) built into the visualizer tool, but you can also load in your own animation sequences to play. I plan on making some programming tutorials or challenges that use this tool.
