As a "side-effect" of my learning process I made a simple "water_wave" using a Lens object.
I think it came out nicely and maybe someone else would be interested to use it.
I will use this effect on a educational game for a local Museum of History. It will be played on a touch screen. And on touch screen this effect look really cool! :-)
P.S. The goblin character is also a "side effect" of testing another software (Zbrush)
