I was thinking of using something like the water effect to reflect the upper screen part of my platformer, but I can�t think on a fast way to do that to all the objects on the screen. ;]
Rojoround did an example with the canvas plugin one time, I tought the shaders could be an interesting way of achieving the effect, but now that I�ve researched a bit I think they are a bit complicated to me yet, hahah
