In 2006, I created this image in celebration of TNG's 20th anniversary:
(<Click for bigger)
I've thought for several years now that I should create something similar for Trek's 50th, but I've gone with a different simplified style:
So far, I've compiled a list of *well* over 50 notable and distinctive species in all the series and movies. What I mean by distinctive is that they are easily identified in a simplified form. For example: Betazoids and Iotians don't qualify because they don't look much if any different from Humans, but Bajorans and Vulcan do qualify. I already created a thread in General Trek to help me see if I happened to miss any important ones, but now I'm moving this here. I've already done the first 25, and you can see a sample above. I'm only doing 50 because, well, 50 years - 50 species!
I suppose at this point I'm just looking to see if anyone has any *good* reasons why some of the top 50 should be changed. Plus comments on the artwork!
