I was reminded of a true story from a friend who now has been a
successful, professional, representational painter for some years.
When he was a student in "a famous art school" in the seventies he
was required to pass his oil painting class, he had to do a purely
abstract painting. He had put it off until the last minute having
done all the other requirements. So he went down to the hardware
store and bought a piece of plywood, a can of spackling, 2 cans of
spray flat black and a tube of wax gold leaf. He spackled the
plywood randomly, then sprayed the dry spackling with the black then
rubbed a touch of the wax gilt over the high points.
When he turned in his masterwork, it caused quite a stir. The art
professors were all a stir and they talked seriously about adding it
to the school's permanant art museum collection. Finally they
determined it was perhaps too "dark". So my friend took it back to
his garage, shut the door and chopped it to pieces with an axe. From
the museum to kindling by a hair.
