I like the windmill one that pops up and you blow into the webcam and the sails turn

i like the green ogre/goblin one.

Kind of a bummer you need the software to make it work.

This one is pretty cool. All you need is flash.

I got it working by taking a photo of the shape on my iphone and holding that in front of my cam - it was the goblin one I think.

This is a really neat idea.
There will be a hugely successful advertising campaign using this idea soon I reckon - getting your audience to interact with your advert - awesome.

i drew the shape with a sharpie.

This is the Wii breakthrough of the internet interactive media

Can't wait to get my hands on these applications and try making a tennis game

Lots of Physics to calculate the trajectories and the oaths and to pass it over to the server to interact with another player over the internet
