[Nfb-science] A Question of Shape

[David Sexton]

Hmm, Well, to do it in excel you might be able to do something like this 
post about filling cells with random colour...
I don't know much excel programming.

If I were writing a program to do it I guess I'd have it first draw the 
grid, then decide randomly which cells should be divided into triangles, 
then decide randomly which squares should be red or black.
No idea how to do triangles in excel...
There are a few imaging libraries for python that might work...
