Not sure if that also,supported re-trading/coloring of the pixel. That could be a nice touch or very against the idea of the others which meant to be "forever". Not needing a special browser is nice.

I might miss it but it seems this page assigns me a single pixel, or one pixel at a time where I can control x,y? The power of the others lies in being able to buy multiple pixels in a controlled fashion and having an easy way to add your logo (jpeg/png/...).
