hdri globes question?

[gazmon]

I was wondering how those chrome ball things work. I understand the theory for capturing hdri images light etc but how do you get it from the chrome ball onto the computer??? its probably a stupid question but its bugging me!
cheers

With the aid of a camera, and a steady hand.
Preferably a digital one... The camera that is.
