I built the block, and Mario to punch the block, and a super mushroom. I broke it down and made Fire Mario, with a fireball. I made Samus and a Metroid from the NES Metroid. I gave it a rest for a while and folded origami instead. After folding 1000 paper cranes, 2 giant epcot balls, and a bunch of other shapes I got sick of origami and moved back to pixelblocks. I bought a set with 1200 blocks and a few more colors than I had originally and started building more. I build in between calls, on my lunches and breaks, whenever my mind and hands are not doing something else at my desk.
The 8-bit canvas is a vast one, and if I get creative I can attempt some 16-bit characters as well.
