Glad you liked it.

Me too :-)

It's fun. It gives quite surprising results really, even when you
understand the physics behind it (the projectile is just going in a
straight line, but it really doesn't look that way most of the time.)

I nearly added air drag- that would change the behaviour somewhat (makes
it a bit more earthlike I think)- but never really got around to it.

In one sense it's a bit unrealistic though- the projectile usually
travels quite fast (probably one hundred miles per hour or more), in
normal everyday experience you would only see a tiny fraction of all
this weirdness; and as I say air drag would minimise it too except for
very dense objects.

I probably should add a list of fun things to try underneath.

Thanks again.
