jurek: I'm glad I'm not the only one to notice this. Spherical boards can be contstructed of course, but they're always a bit awkward, since you can't tile a sphere using only squares, with four squares meeting at each vertex. Either some of the squares will turn into triangles, or else there will be eight vertices where only three squares meet.<p>

Fencer's position on this issue is interesting, to say the least. Obviously not everyone knows what a sphere is (or what it isn't). Given a choice between encouraging people to learn something and dumbing down this site, Fencer seems to prefer the latter.<p>

Of course, another solution would be to sidestep the whole issue and call it "Wraparound Froglet" or something similar.
