### where are they going so fast in those cars?

recall that the primaries R, Y, & B,
together with the secondaries P, O, & G,
and the ideal M (“mud”) can be put in
the “mister big pie, oh” (don’t quit ohio)
order (and looped around pacman style endlessly):
MRBGPYOMRBGPYOM…;
the result, very pleasingly to me, is that the
“lines” of the 7-color-fano-plane can be computed
using “two steps forward, one step back” (so that
by selecting, say, “B” as our “starting point” we
get “P” by stepping forward twice and “R” by stepping
back once;
one confirms on the drawing… or verifies by computation…
that {P, R, B} do indeed form a “line” (the point is that
*all seven* “lines” can be found this way [start at any of
the seven colors and “do” 2-up-1-down as above]).

the lines (dropping scarequotes) are
the “blends” {R, O, Y}, {Y, G, B}, and {B, P, R},
the “blurs” {M, R, G}, {M, O, B}, and {M, P, Y},
and the Ideal {P, O, G}.

i’m pointing at some lines on
the MRBGPYO nested-circles diagram.

our medium is color on canvas.

1. it’s always worse than you think

2. of course not. that’s where that link went *at that time and place*. god dammitl;

3. vlorbik

i should have saved the source code. what stupid make-it-harder-still crap will they come up with next. please don’t answer.

4. mouses that move around at random

5. the end of online life is near. repent!
