Infinity Sphere

When I first got the Encyclopedia Magicas I found a Spelljammer
supplement that was on the drawing board but was never published. It was
called "Infinity Spheres". There were four items from this unreleased
supplement that made it look interesting.

Does anyone here know who was the designer for this supplement. I have
communicated with TSR concerning this because I was trying to get a copy
of the material, even if it wasn't complete, for my personal use.

Any imput would be appreciated.
