interesting, I like the idea but it does seems like it could get really buggy, since pixels turn dead My approach was to split the screen into various sizes In one dimension a 2x2, then another dimension with 4x4 then 8x8... and so on And each cell is a boolean value, 1 if there are pixels in that cell and 0 if there are not With this kind of indexing, i'm expecting high performance, we'll see tho
