Wall Drawing 797 is a conceptual artwork by Sol LeWitt consisting of instructions that anyone can use to make a drawing. I found this at The Kid Should See This1 and I cannot improve on their description:
How does one person’s actions influence the next person’s actions in a shared space? Sol LeWitt’s wall drawings explore this intricate visual butterfly effect in the collaborative art entitled Wall Drawing 797, a conceptual piece that can be drawn by following LeWitt’s instructions. (He died in 2007.)
“Intricate visual butterfly effect” is such a good way of putting it. I have a huge wall right above my desk…I kind of want to make my own Wall Drawing 797 now.
You should be reading The Kid Should See This even if you don’t have children. It’s always so good and interesting.↩
