When the kiddos were here I ordered some puzzles one of which was a 3x3x1. I've had a floppy cube that I have no idea where it is now. I have a super floppy which when you have one edge isolated it will not turn. But now I have one which will. I used to think the floppy cube was unlike any other puzzle. But in the last couple days of fiddling it has occurred to me that it, especially the new one I got, is simply a middle layer of a 3x3 cube. I used to think it had a center, 4 edges, and 4 corners. But now I see that what I thought was the center is really like the core of the 3x3x3. And what I thought were edges I now see like centers of the 3x3x3. And what I thought were corners now I see like edges of a 3x3x3. I can play with it, scramble it, and solve it as if it is the layer between the front and back layers of the 3x3x3. You can do EPS with this thing! You can do Sune with this thing! It has become my latest favorite puzzle diversion.
