A similar responsive background for osu!supporters but with multiple layers with transparency support.
The idea is that each layer will respond differently to the movements of the cursor. The further most layer will move the least while the closest one will respond in a similar matter as the background does right now. This will create a sort of 3D immersion from the movement of the layers resulting in some awesome effects.
With the combination of multiple pictures creating an animation for these backgrounds, some really cool effects could be achieved. Although from the sheer size of such pictures changing rapidly, it would come to performance issues... but I believe you can fix it with some coding voodoo.
