Looking for smart!Sheppard fics

[neqs.livejournal.com]

Hi, I'm looking for fics where Sheppard's intelligence and/or aptitudes play a big role:

1. AUs with him as a scientist or eccentric genius, like No Good Deed by forestgreen or Teamwork by Magus Minor.

2. Fics where he comes across as just plain awesome or badass, like Ties That Bind or What Might Have Been by keiramarcos.

I'm *not* looking for fics where John's intelligence/badassness is given just a passing mention or a surprised reaction - I'm looking for fics where they are central to his characterization, even central to the whole fic. I'm also not looking for MENSA-verse fics in general, but if you can think of a nice, long, John-centric one, why not?

Slash is preferred but gen and het are fine, the longer the better. Thanks in advance!
