Pinwheel Chess was invented early 1970s by me, in NOST/Algia.

The idea is, it's grid chess, but each grid rotates 1/4 turn after each move; and alternate grids rotate backwards -- e.g. a1 goes to a2, and c2 goes to c1.

I wrote the program that displays the board and lets 2 people play, more than once, in different languages. Long lost, of course, even if you could find compilers/interpreters for those languages.

Orbital Rotating Grid Chess is like Pinwheel Chess except that e4,e5,d4,d5 is one cell, (so far just as in Offset Grid Chess, but...) and the other squares in c4-f6 are another cell, and the remaining squares in b2-g7 another, and the remaining squares in a1-h8 (in other words, the 28 edge squares) are another cell. And they rotate in opposite directions. Chaos!

Knight's Tour Rotating Grid Chess, not the right name, but you take a Knight's tour, and each turn the pieces on a1 move to b3 and the pieces on c2 get transferred to a1, and so forth
And finally, Brownian Motion Chess, where the squares are randomly inserted into a linked list, unknown to the players, and each turn everything moves forward on the list one step.
All that was from just one of my densely-typed two page articles in N/A in early 1970s.

I have all the back issues, and some other stuff, packed in a box to send them away, but I never get around to doing it. So nag me.

Critique: Pinwheel could be played postal, which was the only mode back then, but you'd be crazy to try. Both pinwheel and Orbital should be playable (and even fun!) in a noncompetitive online situation.

Knight's Tour is just an over-the-top thingy all us CV designers like to do, and Brownian Motion is over-the-over-the-topmost.
