Woah I must say I'm incredibly jealous of these amazing cages.
Mine is a pretty standard 2x4, I want to expand some day when I'm no longer living with my dad. I just don't have much room in my bedroom.
I want to add a loft pretty badly. I just checked the guineapigcages.com site to find ways to make a ramp and in the store they will actually make one for you for a price. This pleases me greatly.
Okay, enough rambling. Here's my cage.

I put an old fleece blanket on one side of the cage because it gets really cold at night. There's some cuddle cups and some extra fleece to burrow in underneath it. The girls love it.
And I just wanna say how much I've grown to hate pigloos. I really want to get rid of them.
