Yenka and absorb Content
Yenka is a plug in that enable the user to create, purchase and use content for Mathematics, Physics and technology. They have a limited free player that allows the user to create and manipulate 3D schapes, changing dimensions to get volumes, opening the shapes up etc. I see this being very useful and powerful on a smartboard. The free version also lets you do basic circuits.

They also host a large quantity of free Absorb Content - these are neat little applets that you can run of the website for science, technology and mathematics . When I checked there were 729 different elements of content. You cant download them but you can play them from the site for free.
