Move your cursor (or finger) around the screen, and Mario will look at it. What is that? A super mushroom? Hmm...
Looking at @m30w695's original project, I got the idea to do the same thing but with the Mario from the original Super Mario Bros game. I took the original 2D sprite, saved each row of pixels as a separate costume, and then expanded each pixel row into a slice of a 3D model. The top of the hat is 11 pixels high instead of 1, because otherwise it wouldn't be visible, but other than that the sideways view is precisely the same as the original image.
