App Pick: 123D Catch
Alex Lindsay's pick of the week on MacBreak Weekly 505 is 123D Catch from Autodesk. This is a free app that lets you create 3D scans of nearly any object. Just take a bunch of photos of something from all different angles, and it will build a 3D model of it. Then, if you have a 3D printer, you could print these objects as well.
