Site with absurdly powerful characters for D&D 3/3.5

A good ten years ago a friend of mine told me about a site somewhere where absurdly powerful characters for D&D 3/3.5 were listed, with detailed level-by-level character progression.

As far as I can remember, it included characters like a mage who turns into a beholder with a beholder’s full powers, and a four-armed humanoid that hits for over a hundred damages with a regular spear. And all of it perfectly legal: they just combined every handbook’s feats and spell with each other to exploit all advantages and synergies.

I’ve never been interested in powergaming so after a cursory glance I dismissed that site: but now I’d wish to find it again to show another friend and who’d wish to take a look himself.

Do you know what site it could be?
