Becausr the full-res version links went down often yesterday, I'm hosting it on my IPFS node, here's the link (for those on IPFS, if you can afford the bandwidth please pin it to spread the load :) )

Alternatively, if you have a slower connection I made a lossless webp here which should result in the same output at about 1/10th the size: http://files.jjcm.org/mosaic.webp
Also made it available in torrent form (with the IPFS URL as a web seed) http://www.urlhash.com/124410/mosaic.png.torrent
