Web based Flash like animation

Today i have found flash like animation creator tool , that too web based.

This reminded me of my days at college where i used to work on shock wave tools to create simple animations.

This tool is available at

Give it a try.
If you know how to create flash animation, it would be very easy, else try ur hands ...

Good Luck
