I got the idea from V.I. Arnold’s Real Algebraic Geometry, where he multiplies lines together (e.g. and ) then increases the RHS above to create disconnected shapes. Can make pretty much any shape that way. So immediately I thought of chess boards.
Well, this was my first effort in the area:
Then chess boards.
gives the “traditional” square grid; increasing the RHS from makes the squares gradually circular, eventually the central ones disappear. (I used Mac Grapher for these pictures; it has problems drawing it accurately, even on highest settings.)
10000 (although I haven’t tried to play on it yet!) seems a good balance between craziness and playability:
Or in coloured form:
Well that looks awful; I turned the original into b&w which messed up the smoothing. Will do a better version. But you get the idea.
Another try with some border lines added; I thought it might slow down the (possibly excessive) circlification in the centre:
I would have made them closer together, but Grapher can’t draw that at all.
Next: Why not just use circles. Or those squarish circles with ?
