### Re: Rotating axis in 3d.

I expect that you record a position at the start and then rotate by an angle proportional to the distance from the starting point. I figured, but how is this proportion computed? I only have x and y coordinates. If for example you drag down on the window, it will rotat the y axis down, and the z ax...

### swapping values

Today I ran into a neat trick for swapping values. It's not necessarily efficient, but it's neat nonetheless. For example: a := 12 so in binary 1100 b := 17 in binary 10001 a = a\oplus b so (in binary) a = 11101 b = b\oplus a b is 1100 a = a\oplus b and a is 10001! I can't figure out how this works....
