Love it. Very cool.
Brings back amazing memories from when I was in high school. A friend invited me to come to the museum for some drawing thing, turned out I got to participate in making a Sol Lewitt drawing. Had no idea who he was at the time but it was such a unique experience.
We were in an empty gallery room with a (I believe) BLACK painted wall with a faint grid on it and we were given an old hat with a bunch of cards in it. There were 4 or 5 highschool kids and we each took turns drawing a card out of the hat and drawing the shape from the card on consecutive grid squares on the wall. The shapes were basic lines and semi-circles. It was lots of fun and the end effect was a very beautiful line drawing mural.
