I had a read, but it didn't get me very far, sorry – competing with
an Alan Kay presentation is always going to be tough :-) Regarding
Physics, it's more a sandbox for making weird and wonderful little
mechanical devices; but specifically regarding gravity, I think there
is a nice feature I'd like to try and find a way add as some point,
'object trails'. With this you could roll a ball off a cliff edge and
see the motion curve left behind. Would be quite easy to add a grid
overlay to allow measurement. I guess an optional gird would also
allow building other more accurate experiments (i.e. I just made 3
pendulums of different lengths to see the shortest pendulum swing
faster; and that using a larger mass weight did not affect frequency).
