Rewriting SuperPi

[Calmatory]

So, you know HOW to do, but you don't know WHAT to do?

What about doing soemthing GRAPHICAL instead? Software rendering.

What about doing the "plasma effect" from oldie intros/demos? Don't use LUTs, calculate everything over and over again for every pixel, with cosines and sines.

Basic idea goes like this:
go trough every pixel in the screen (with for(){}'s).
calculate pixel color (e.g. c = 128cos((x*y)/120)*64+sin(x/50+y/30)*48+cos((y/x)*60)/16
set pixel on the appropriate point on the screen(direct framebuffer access would be way faster though).
loop for 2 minutes.
calculate the amount of rendered frames.

You can put huge amounts of load to a CPU if you don't use LUTs and use big resolutions. Think about 1600*1200*10 trigonometric functions in one second. Too fast? Add more complex formula.

It doesn't really matter what it renders, as long as it renders, with CPU. I'd be interested to watch some kind of an effect rather than "Calculating... Please wait..."-text for over and over again. Oh, and whatever you do, please, do it cross-platform in mind.

Or what about image rotating? HUGE maze generation? 3D rendering? Fractal rendering? There is SO much what you can do, just be creative.
