Art

Art-art. The mostly flat kind. Not strictly 2D, but 2D adjacent. Mostly stationary. Possibly your granddaddy's idea of 'art'. Kinda. Quasi-2-dimensional self expression in visual form. I caveat because paintings can be dimensional and so can body art, and so is some of the weird mixed media stuff. Also, no offense if your granddaddy was DuChamp or something.
