Yo, the base rig is by a guy called Brad Noble, I bought the scripts that you can use to resize the rig with, so all the humanoid characters are rigged on that set up with me resizing it and skinning the particular character.
I'm using a rig by Brad Noble, and I paid him for the resizing script so I could use it with a huge range of characters. Can't do any work atm, but I'll be back home in about 3 hours and I'll get back to the grindstone.
