Hat tip to Bruce.
Joshua Davis once gave the coolest design lecture I ever attended. He talked about putting red food coloring in his eyes (result: cool looking eyes, mild discomfort, tears that looked bloody and a red tint to his vision for a few hours) and the process of doing his art (experiment a lot, use math, make interesting failures, build on what works). Then, he invited us to play, too. Play is the opposite of poverty.
