A meditation on the physics of barrel cannons and Aristotle (as I recall, he was under the impression that things going sufficiently fast were unaffected by gravity. Not too far off from Sonic the hedgehog, for that matter, who has a tendency to run along flat ceilings). Disjoint Physics. In practice, it might be more effective to implement this sort of behavior with durations, rather than piecewise handling of velocity, but it’s an interesting effect either way.
