Two notes for impossiblator 2: If you're going to attempt to calculate pi again, here's some more digits for reference - I notice you missed a few iterations of whatever.

Also, your raycaster suffers from fisheye. I think you take the distance and divide it by sqrt(x^2+w^2)/w, where x is the row, and w is the width. Or something like that. It's probably doable without using a square root, but not without squaring or without dividing.

But yeah, what you do really impresses me, and all I can really say is... keep up the good work.

Needs more comments describing awesomeness of this man.

good job
