where is?

The actual Insimenator mod? is it a myth or something?

Scroll down the main forum page.  It's about half way down.  It's no longer supported since the creator did his traitorous act.   A bit of advice, I wouldn't ask anymore questions about it. 

The Sim Blender at Simbology is almost the same and is supported by the creator Two Jeffs.  Google for his site if you're interested.

To be more specific, it's at the bottom of the "Community Downloads" block if you're looking at the Forum view.  Use at your own risk... as it's been said, it's no longer supported, and anything that may or may not happen is something we won't be able to help you with.
