Awesome!!
I really appreciate this flash and its work.. The research done and everything to complete it.. Sure, its not an animation or I cant compare graphics with flashs like Super Mario Z or whatever.. But seriously.. Writing down all those details and getting it done that well deserves respect!! Too bad I'm at university already, or I wouldve asked you if I could use your flash for a school project =P
You should do something of the human body.. maybe a skelleton, then veins, etc (well.. I think the human body is a tiny bit more complex than the universe, haha)
