Melting Men, an ice sculpture by Brazilian artist Nele Azevedo, is simply 'cool' (Sorry about the pun.)

This public art installation consisted of hundreds of sitting figures fashioned out of ice. When the last man melted it was the end of the project.

The ultimate in disposable green art - what I really do like about this is that it really does leave nothing behind.
