Wondering if someone can help me out with an interactive rotation. It ideally would emulate a realistic gravitational rotation.

i.e. if you were to take a book from a shelf by holding it’s top corner, it would remain horizontal until it reached the edge of the shelf, and then it would drop (pivoting were you’re holding the book i.e. top corner)

I hope this makes sense. I’ll try to create a mock up to explain whenI’m back at home.

In the interim, if someone knows what the hell I am on about, please post links/or “where to start” pointers.

cheers.
