let me give you a little background on this painting/perler bead mixed media thing.
acrylic on stretched canvas with perler bead sprites on magnets.
the background is painted 16-bit. i just painted a regular background. no characters sprites were painted in this painting. all the characters and objects were all made with perler beads (these are in my perler bead photo album). i then glued magnets on to the back of the perler beads. then i put an opposing magnet on the back of the canvas so the magnets on the perler bead guys would stay.
this is essentially an artistic moveable video game screen. put the sprites anywhere your little heart desires. endless possibilities of recreating the scene, especially if i would make different characters like tanooki mario, hammer bros mario, koopa's, warp pipe, etc...
