I have a vague feeling that there is a few live programming (and similar...) demos that use projectile/cannonball movement - but I cannot seem to find any now that I need them 🙂 does anybody here know of some examples?

Probably not what you're looking for but there is a demo of Eve where they build a bouncing ball simulation:

This is nice too - but I think there was something else.. @Joshua Horowitz wasn't there a cannonball demo in the programming tool whose name I forgot that you showed a couple of times? (something starting from A...?)

Oh gosh – I always wanted to add a cannonball thing to Apparatus (as a test case for creating & destroying objects), but I never got around to that. Is it possible that’s what you’re thinking of?

Ah, yes, it was certainly Apparatus I was thinking of, thanks! I was thinking I saw a projectile motion of some kind demo in it? But perhaps not...
