I've recently been really interested in paper craft models. I built my first one last week (tiny Cthulhu, pictured below). I've never really done these before but I think I will get better with practice. Check out paperKraft to see some really cool models. On my list of pieces to work on: Koroks from Legend of Zelda, Pikmin plant guys, and maybe a Big Daddy from Bioshock if I manage to get up to that level.
