I received a few dozen Star Trek Minimates as a result of selling a ton of Star Trek related material on eBay. At first, thought what on Earth am I to do with these? Then, I realized they seemed quite interchangeable and rather easy to customize. I elected to focus on minor characters from the original series. Using the hydrocephalic U.S.S. Enterprise I chose to focus on the doomed sister ships of the Enterprise--since the same set was used to represent the bridge of those vessels. I know these are not masterpieces, but I think they make a fun hobby.
