Original design I did yes, but what you see there is 80% Zombie work. Hacks, changes of the original design, additions, etc. There is so much he put in that forum that it blows my mind. Props to him.
Not a huge fan of light-text-on-dark-background color schemes, but considering the subject matter it seems entirely appropriate. The green-on-black reminds me of an old computer terminal -- actually, it's a neat effect. Great custom graphics.
It might be nice to see a somewhat lighter table border color; maybe the same green that's used for the buttons. Then again, maybe not ... the site is meant to be DARK, and green borders would clutter things up a bit.
