a couple nights ago i read bryan chung’s lessons on augmented reality and optical flow; i loved the reading and felt the urge to code something similar.
after a little casual tinkering, i found myself playing with an optical flow algorithm, a couple trig functions and a basic flat physics mini-engine; “wait a minute”, i said, “this is arkanoid!”.

so here it is:
