I've always been impressed with the Sonic the Hedgehog Papercraft available at Japan's Sega website, but since I'm a Mario fan-boy, I was also disappointed that I could never find a Mario equivalent. I mean, there are some Mario papercraft figures, but not a level diorama like the Sonic one.
I had some free time on the weekend and have whipped up this papercraft diorama model of World 1-1 from Super Mario Brothers. It's more-or-less to scale, too.
If you like it, stay tuned because there are more on the way.
