From Jeff's website, in the Torus Games source code zip, there is a Revisions History file that lists Jan 2006 as "Initial Torus Games 2.0 release." I've tentatively set the invention date for this game as 2005.

Thanks for checking!

After some digging, I managed to find a copy of the first edition of "The Shape of Space" from 1985, and it turns out that it already has the same variant displayed there, so I think I can set the invention date even further back.
