I was surprised to find out that there is an official Transformers Sim in Second Life (http://secondlife.com/), so I had to check it out.
The area is not that large, but probably fairly move accurate.

Inside Sector 7 (that's the name of the region)

A giant sized Megatron

They are giving away free Bumblebee avatars, so as you can imagine, there are Bumblebee's everywhere o.0
it's an awesome sim, very dtailed scene from the road on the bridge, the exterior and then the hidden lab, first time visitors i'd reccomend using the lift to get a sense of distance, tho after the first time... teleporters are much much quicker :P
for anyone else in secondlife wanting to find the place, look up sector 7.
(yes it actually is an official transformers sim, run by the real deal)
