Catmap

A project that takes an image I've chosen and applies Vladimir Arnolds mapping to it. May use pixels instead of vertices in the future. Right now I have the shader mapping all the vertices somewhere else, exactly 2x and 0.5 y. I then take those points mod the number of vertices on each edge, which brings them back within the range. After doing this a magic number (192) of times, it returns to more or less the starting image. Performance will remain buggy until they send an assassin after me.
