computer programming

So we've started on programming using the program "processing" it seemed reasonably daunting at the beginning especially after Jitter but it doesn't seem so bad everything makes relative sense except that some values such as transparency wouldn't be from 0 - 100 but from 0 - 255 which was just a pain. Also rotation and arc's were a right bitch because they were measured in radians and not degrees and also didn't specify where the start point was just to make it harder.
