Well, I watched Star Trek Into Darkness last evening, and because I'm a Fan of Star Trek I decided to do a few Mocs. So did the Enterprise and the Kelvin. I added a stand to each model, so they are perfect for your desktop.
Step 1: LEGO :: Star Trek: the Enterprise
You will know this spaceship definitly. It is the legendary Enterprise.
Step 2: LEGO :: Star Trek: the Kelvin
This one is not so special. It's the Kelvin of the second-newest Star Trek film.
