Perhaps spurred by the Trek 11 ship leak, some heads at Relic Entertainment's message board decided to come together for an
art thread to redesign some trek stuff.
One of the first challenges was redesigning the Enterprise. This was my take.
I also did Klinks:
...And Romulans (The D'Deridex)
There's more in the thread, including some props (Phasers, Bat'leths, and so on) and alien races (there are impressive takes on the Klingons there).
The current spaceship challenge is to redesign the Vulcan ships (ENT era), but finals is getting in the way of me presenting anything.
