Make a card for which corner A is labeled A on the front and back and
is painted red on the front and back, corner B is labeled and painted green
on the front and back, corner C is labeled and painted black on the front
and back and corner D is labeled and painted blue on the front and back.
A second way to consider an "element card operation" is to look at the
"Geometry Action on Any Card". You can see this Geometry Action
in each "element card operation" defined below where the ACTION is taken on
the starting (IDENTITY) card. Also consider the example below of one
"element card operation", m, followed by a second, R, giving the same
overall "element card operation" achieved by using only one, V.
You may use your own large square card and turn it in a real time way to
have yet another method to work out the ideas in this project.
