Did these two quick models last month… and uploaded to shketchfab.com
The first is a “Door”, a technology used by the Carrier(orbiting space station) in The Authority.

The Authority is this neat comic series by Warren Ellis and Bryan Hitch. Its about a team of super heroes… thats a bit more dysfunctional than your typical comic book super teams.
The second one is a 3d version of my favorite graphics from the game Portal(and Portal 2)

of course i’ve yet to model the most popular of these portals/doorways - the Stargate… will do that sometime soon!
