Time has come to release my own simple contribution.
As always, no time or motivation to polish with more stuff in the background, a music playing or a scrolltext, just the main effect I wanted to code.
It is something I wanted to tried many times before (I have already seen it in demos though), a 3d grid of shrinking and fading cubes, two effects running on the grid (if you let it run for a little while). I even use some shader to fade near the edges of each single cube and give lighten electric edges like tron or something. I could have used a texture but I like this direct shader method.
