Rainbow Mario

This is a skin for Mario based on his appearance after picking up a Rainbow Star in Super Mario Galaxy. It animates fully between 7 different colors!

Unlike in Super Mario Galaxy, this skin will not leave afterimages as Mario moves. It also appears somewhat more metallic than in the original appearance. Additionally, the skin may appear to glow somewhat, particularly on stages with bright or intense lighting.

There is a video preview of the skin to demonstrate how the colors animate. Keep in mind that this video was taken before several adjustments were made to the skin, and so is only accurate to demonstrate the color animation effect - the screenshots, however, are accurate previews.

Special thanks to Kerouz for the excellent UI and the video!
