3D printing: with 2D; with holograms; and all-in-one 3D scanning

Here's a video from last week's Maker Faire showcasing technologies for printing out 3D-ish objects using 2D printers: ModelBox turns a 3D model into a series of 2D images you print on acetate and set into a frame to cheaply and quickly prototype/simulate the 3D object; Zebra Images turns 3D models into holograms; and Lynx Laboratories demos its all-in-one 3D scanner.
