With custom software developed using openKinect and openFrameworks, Be Your Own Souvenir by Blablablab let people pose and generate action-figures of themselves. Three kinect sensors captured 360 degree scans of each person. Meshlab used the combined input pointclouds to create a Poisson reconstruction (cleaned via Blender and Skeinforge) before sent to print.
With the price point of 3D printers going down, imagine we'll be seeing more varients on these tangible representations of self. To my friends designing that mega candy store, I think 3D printing of visitors into candy statues would be a hit.
