Cubify have teamed up with the Star Trek brand making it possible to have your own head on a Star Trek figurine.
A really simple wizard guides you through selecting the body types and uniform then you upload a front and side view picture of your head. The figurine arrives back in the post. A bit pricey but great for convincing people you starred in the series!

Prototyping machines have been moving into production for some time. How long will it be before we have our head scanned in the optician and walk out with eye glass frames that fit us exactly with no adjustments needed?
