If I'd pass the exam, obviously. But I HAVE to.
In the meanwhile, between a Jacobi and a Gauß-Seidel, I found a way to learn OpenGL applying cellular automata! These are the results:

...my first "demo"! I always idolatred the demoscene and their works, I consider them true genious and real Artists. Naturally, I'm very far from them. This is kinda tribute.
Some demos/intros are pure mathematical poetry, absolutely brilliant and one of the few demonstrations of real powers of a modern computer. Nowadays none optimizes, studies in depth processors and spends his time squeezing any cycle from a CPU: that magic is gone.
I miss it very much.
