There is a website called footballasfootball.com that makes soccer badges for all NFL teams. Here is an example: I decided to try to make some for the Rockets using a few as a template: Just thought I'd share.
I'm a fan of the last one and would be interested in wearing a t-shirt with the logo EXCEPT for the fact that the Apollo 1 fire occurred in 1967 and nerds such as myself could mistake it.
I really like this one. Just a FYI the stars in "football" represent every 10 championships. Since the NBA is still relatively young we should have 2 stars for our 2 championships.
I like the Shuttle logo you used, would be cool if when we go back to red and yellow and change design a Space Shuttle is in them.
