haha! you're a two-fold champion:
1) for ragdolls (i know Helghast has his, but good onya for doing your own and taking a different approach). i'm keen to give newton physics a go when i finish school, so i've been keeping an eye out for good examples!
2) for actually getting one up at youtube so quick
for me, at least, it's so much easier to watch.
my first thoughts were of the game "skate", on ps3. have you checked it out? very good game. probably your kinda thing. uses the analogue controls to do tricks -- much better than button-mashing combos in "tony hawk's".
apart from a few jolts, it looks good! the arms are pretty rigid, which i guess is due to the hinge-work, but i reckon if you add intermediate shoulder bones you might be able to get more flexible arm joints?
i'd like to see this integrated into a skate game
good onya,
