"Den beinahe barock anmutenden Strukturen, auf denen sich das Licht durch das Wasser bricht, beruhen auf mathematischen Formeln."

Background
I thought these were interesting shapes, so rendered a fly-through. Not very special in and of itself, I tried to add a second layer with caustics - by rendering a moving caustic map in After Effects and using it as an animated texture which I lit from underneath. This layer I added on top of the regular animation to create the effect of a water surface somewhere below.
Another thing I did is frame-blend it to 60fps - which actually makes for very smooth motion but loses its cinematic quality as it looks more like something a game-engine would produce.
