This was a quick little one-evening project where I challenged myself to grab a sprite set off of opengameart.org and do something fun with it.
I ended up grabbing a really awesome sprite sheet of pixel art pipes, and implementing a simple drawing app that lets you draw with pipes, and updates the pipe images as necessary based on the number of inputs to each cell.
Nothing too complex going on here, but a fun little experiment, nonetheless. To try it for yourself, head here.
