For those that dont know TED is a conference for the best inventors, scientists and general ideas around at the time.

The posted link is about a directional speaker (it has been around for a while so you may of heard of it before). Although this is an interesting topic i was posting mainly for the section on the millatary use of this (as units have been sold for use in iraq). They use the directional speaker to play scripture into terroists heads without others around hearing it, or making false troop noise on a hill miles away. This just seems so wierd and cool, imagine standing there hearing a voice no one else can hear xD.
