This is not a map that you play normally, but it's cool to see a crazy pattern. You can actually avoid most of it if you sit in certain spots, and when you do it it's super satisfying. Not good quality, as the map is only 40 seconds, but fun to try out.

Similar to the Touhou experience. It has what feels like random patterns, but also has some cool patterns with it, making for an overall fun time.
