Huh. Coulda sworn I already uploaded this...
Some old nerdy craftage, with close up shots of the vectors I made for the cubie faces. I actually put on some shiny clear coats after I snapped these pics.
Green - Triforce (Legend of Zelda)
Blue - Starfox logo
White - Kirby face!
Yellow - Pokeball (Pokemon)
Orange - Samus's logo (Metroid)
Red - Mario hat logo
EDIT: If you'd like to make a Nintendo Rubik's Cube of your own, I've uploaded a PSD of the 300 DPI template to use. You can grab it by using the Download File link on the right. It'll look small when printed out, but once you cut out each square, you'll see that they fit on a standard size Rubik's Cube just right.
