While sitting where you are, draw your kitchen, don't go look at it yet. After you've drawn your kitchen from your seat, get up, go look at your kitchen, and draw it again, this time while you're looking at it. Now, sometime during the week, when you're at work or school, on the bus or in a waiting room, draw your kitchen a third time.
Post you're drawings here, I'd love to see them.
[final note: I'm unofficially continuing from where they left off]
