It's a shame you picked q3's fast inverse square root. It's not a great example as it turns out someone else implemented it in Quake 3 and someone else entirely devised the algorithm itself. Though you're right - he's a bit of a hero and deservedly so.
edit: however ... I've just read that article and it is actually the most in-depth and interesting analysis I've read on the subject so thanks!
