I love the person daring enough, playful enough, to use their own walls as a canvas for an abstract painting. Also, pink and orange is a truly winning colour combination. Can’t afford giant art? Invite your friends over for a painting party. Give them a wall. Some brushes. And a palette of your favourite hues. If it’s not the Rauschenberg you hoped for, just paint over it, and start again. It’s only paint, after all.
