Like the swine flu there seems to be a lot of this about at the moment and although the first one I saw I was seriously impressed, this is obviously an indicator of where things are going, but I do hope that people start innovating with this technology rather than jumping on the wagon and using tech for tech's sake. And to be honest printing out the anchor, setting up web cam and playing with the damn thing seems to be to much of a hassle when you can watch the effect on You Tube.
Luckily for you I have posted the finished effects of the ones I have picked up on below, they range from pretty dull to seriously impressive.
