You're a spring. Think about that for a minute. What would a spring do? Fling, of course. Fling your way through fanciful worlds, scaling buildings, waterfalls, soaring through the clouds and rocketing toward the sky. No, literally, rocketing. There are jetpacks. Also, did we mention there are silly hats?
Video of the main menu system of SpringFling. Not complete but the framework is there to extend this for all other menus. Uses simple lerping to achieve smooth animated fly-ins.
