Nothing too crazy here, it’s one of the question mark boxes from the old Mario games. I originally wanted to make a maze, but figured it would be too hard without the ability to “pick up the pen” so to speak. It would be nice to be able to move the marker without drawing a line; then we would be able to make multiple, discontinuous tubes (unless there’s something i missed).

EDIT: added categories

For a while I was mixing up height and width in some spots, causing some “unique” behavior, so I guess that was one of the larger challenges. I also wanted to get multiple colors working, but was unable to get it looking good. The idea was to normalize across 255*3, and any value from 255-510 would be set as green, and anything above 510 would be blue. That way you’d have layers of colors as you approach the center of a pox. Overall it wasn’t terribly difficult, but it was a good learning experience and I will fiddle around with it more on my own time to see if I can produce some cool outputs.
