Great work by Sagmeister. I really like the idea of transient art.
At the opening of our exhibition at Deitch Projects in New York we featured a wall of 10,000 bananas. Green bananas created a pattern against a background of yellow bananas spelling out the sentiment: Self-confidence produces fine results.
After a number of days the green bananas turned yellow too and the type disappeared. When the yellow background bananas turned brown, the type (and the self-confidence) appeared again, only to go away when all bananas turned brown.
