This art exhibition by Austrian designer Stefan Sagmeister is very clever and inspirational.  The artist mounted 7200 bananas onto the wall, each at various levels of ripeness. It’s a Lego-like building environment, and the greenest bananas contrasted with the yellowest ones enough to spell out words:

“SELF CONFIDENCE PRODUCES FINE RESULTS”

Here is a close-up view of the bananas:

Over the course of the exhibition (January 31 to February 23, 2008), the exhibit transformed from a fresh display of produce to a smellier and browner one. Interestingly, at the end of 3 weeks, you could still see some of the lettering, due to the different degrees of ripeness at the start.

Sagmeister’s website shows many other examples of his clever approach.

Although I’d much rather be eating bananas than watching them on a wall, I appreciate the inspired thought of Sagmeister to even conceive of using fruit to create typography, and then watching it change over time.

Now excuse me while I go make a smoothie.
