Sketch Star

Sketch Star is a cool site that I just found out about from Free Technology 4 Teachers.  This is a great site for creating custom animations frame by frame.  A user has lots of tools to choose from such as: puppets, objects, brushes, etc.  After a frame is completed it can be arranged into order by dragging-n-dropping on the timeline (think iMovie).

I recommend checking out Sketch Star by clicking here.
