I'm getting into Lego mosaics lately, and here's some of the stuff I've made.
For a while I thought that modern Lego had too many colors and it was hard to make use of them all, but now I appreciate them.
I'm not sure which exact version of Mario these are from, since they look like updated Super Mario Bros 3 sprites, and I changed them a bit more to work with the bricks I had available.
But either way, they turned out very shiny, and I'll keep probably keep these around for a long time as decorations. They took about an hour each to make.
