I agree with 99% of this, however I feel like the author missed something and was 100% wrong in one case. When talking about bugs in the simulation state, the author states: > If you resize the window to be smaller you can trap the DVD logo on an edge. Resizing the window in the Animation solution means we recalculate to the correct position. If you resize the window in a simulation state it's trivial to maintain the same general position of the logo. For instance, 80% across the screen or whatever. With the authors code, as the window is resized, the logo goes flying everywhere in what is obviously a bug. Especially if it has been running a long time, changing the modulus will result in random seeming jumps.
