   I made a puzzle game that gently introduces my favorite math mysteries▲1,054

   This is the first iteration of a short game I’m making that tries to interactively explain some of my favorite math questions / ideas. My goal is mostly to get the player curious and not necessarily to explain absolutely everything. There were a lot of fun technical parts to building this: - For implementation reasons, it’s much easier if the lines all have integer intersection points with each other. To do this, when a new line is added I “cheat” by rounding intersections to integers and then splitting the old lines at the intersection into new linds (with potentially different slopes)…

It’s based on a novel phenomenon I noticed where, once these mutations happen a few times, the original region can be hard to recognize. You have a feeling there are symmetries in the image, but they are just out of grasp. Going further, if only part of the region is visible, such as mirroring off the edge of the board, it adds to the feeling and it becomes a satisfying puzzle to solve. I originally published this on the…
