iPad 3D Letters

Two groups arcroos the pond BERG and Detsu London have been developing a software for the iPad thatwill paint 3D letters in by taking pictures. By simply dragging the iPad from left to right you can paint a 3D image in the air so to speak and then photograph it to create an amazing 3D graphic I think that this is an amazing accomplishment as far as iPad technology goes, now you can upload software on your iPad and create 3D graphics without using a CG software. However i think that this is a little impractical because the video that the groups made was about 3 min long and they said they had to take 5,500 pictures and not all of them were even used.
