Is there an instructable on the "not a rectangle", where is it, and if there isnt, is/can someone make one?

I would like to build it, so I would really like to see more about it, because I havent seen more than a few pics of it and what it can do.

There are no instructions for it, but if it helps, it uses the TR stock, handle, and trigger.  The barrel is a simple tube, Mepain has provided close-ups of the chamber with the balljoint in it.
