I've been having fun lately generating triangles with Python, as you do. And the other day I stumbled across one of
Josef Albers'
Homage to the Square. My first thought was, "Wow, the colors." My second thought was, "Those should be triangles."
I went to Google Images and searched for
Josef Albers Homage to the Square and picked three at random:
Ascending, 1953.
Glow, 1966. And
Soft Spoken, 1969.
Then I ruined them with computers by turning everything into triangles:
You might want to take a look at some non-ruined versions of
Homage to the Square, like
Impossibles from 1931 or
this one from 1967.
