Yet another use for 3D printing: Printing Your Head. Yes, this has been done before quite a few times, but HeadBobble seems to have simplified the process and produces great 3D prints in full color. And you get a Bobblehead!
How does it work? At their website you go through a selection process, where you pick a "pose" (wedding couple, singles, etc.) and other standard options, including labeling, logos and such. You'll upload images for the faces, which are then 3D printed with accurate coloring. They'll stick the heads on the bodies to complete the bobblehead.
The costs are highish but not unreasonable for this type of service. The wedding topper imaged above, for example, is priced at USD$189 and would definitely be a hit both during and long after a wedding.
