UPDATE: Ouch, weeks after this entry was published Criteria Systems ceased operating on September 3, 2010! The video was removed from YouTube, so much for their legacy.
Criteria Systems is a company in Calgary, Canada that produces three dimensional images of objects. For one of their demonstrations they chose a trilobite.
The object was 3-D scanned and the process is described at their web site here. Also don't forget to check out their blog.
Very cool technology and it will be great when consumers will be able to take 3-D pictures or scans!
