Give Stefan Sagmeister 10,000 bananas & some glue, and he give you a giant Banana Wall, part of an art installation on Things I Have Learned In My Life So Far exhibition. Titled Self-confidence Produces Fine Results, the Banana Wall is made of real bananas stacked up in a giant wall at Deitch Gallery.

In the Banana Wall, Sagmeister used green bananas to create the motto: Self-confidence Produces Fine Results and ripe banana as the background. The interesting thing about this installation is that it change over time. As the banana ripen further, the motto will disappeared and the background become brownish-yellow. The whole bananas gradually decays over 24 days of the exhibition.
