Interactive students
Ever since I got a SMART board 5 years ago I have been using Interactive physics to demonstrate just about everything in the mechanics part of the course. Watching red balls fly and blue boxes slide can become a bit dull so I have started spicing it up by attaching students to the objects. I started with just heads but a head swinging on the end of a rope doesn't look very nice so now I have attached bodies. All you have to do is find a photo, copy and paste it in paint - select and copy the bit you want - paste it into IP - draw a similarly shaped object in IP - highlight both objects - select attach picture from the object menu.
