The Urban Speaker lets you address the masses without having to stand on a soap box or look crazy in a public place. This public art installation was created by Carlos J. Gómez de Llarena and features a smartphone attached to a speaker that broadcasts whatever the caller says for 60 seconds.

The Urban Speaker is set to make its debut at the 2010 Conflux Festival in NYC. Check below to see the number to call as well as some other interesting info on the Urban Speaker.
