I tried to avoid popular/well-known images and designs at least for part of my design stuff... I pretty much ripped off another, but it's 20 years ago that it was out there, so I don't feel bad. Otherwise I'd probably just have pulled in something like a Hyperion and statted it out and called it good. 

I renewed my subbie a couple months ago and turned my cap pilot into a cloaker-bomber. They've been stuck on stations for a long long time too.
