Since my childhood, I've been a huge Megaman fan. After I moved to Salt Lake City and had nothing on the walls, I was inspired to create some MM art. My first project was a mosaic of MM from MM2 made from ceramic tiles (the kind normal people would use to decorate a kitchen backsplash). A year or so later, I spent a ton of time and crayons making a MMX version. I wrote some code to take an image, overlay a hex packed grid of circles on top, and project colors to the colorspace the colors of crayola crayons (as reported by wikipedia). I ended up doing nearest neighbor interpolation to get the colors of each circle, and the projection is nearest neighbor in RGB, L2 norm. I played with a few combinations, but this seemed to work well.
