Color 3D lattice of blackjack scale

Since Joseph Pehrson found my ASCII blackjack lattice helpful for
composing, I thought I'd make a prettier, easier-to-see version. Go
to /tuning/files/perlich/scales/ and
download bjlatt.ZIP. The notation is:

A,B,C,D,E,F,G,b,# as in 12-tET
] = 1/4 tone up
> = 1/6 tone up
^ = 1/12 tone up
v = 1/12 tone down
< = 1/6 tone down
[ = 1/4 tone down

The various colors represent the same 7-limit intervals as they do in
my paper, _The Forms of Tonality_.
