DIY Fisheye lens from Sigma 28-200mm

Spotted this guy who made a fish-eye lens from a broken Sigma 28-200mm lens:

Recycling Project - A Broken Glass To A Fisheye Lens |

Unfortunately, it doesn't describe which element(s) he used. Does anybody have any ideas about this? Would a non-zoom lens also contain suitable elements to build a fish-eye lens?

btw: I've created a DIY fish-eye lense from the viewfinders of very cheap second hand point-and-shoot filmcameras, and one using a spy-hole lens... both for use with my (non-pentax) digital point-and-shoot cam. Although they're fun to experiment with, image quality is pretty bad.

Here are some shots I took with the DIY-spy-hole-fish-eye lens (and non-pentax point-n-shoot)

Pretty low-fi and it has gotten worse since the exposed plastic lens got scratched in my bag... Slightly better now that I polished it with toothpaste...

Anyway, messing around is half the fun, right?
