[LAU] Slightly OT: Targeted audio beams

[lanas]

Folks,

  This is about thin audio beams that can be sent more or less directly
to one's ears.  I thought the article could be interesting for some.
Of course, many jokes can be made about that, especially if cereal
boxes in supermarkets starts to thus 'talk' about their contents to
passing consumers.

  But then, can you imagine a concert made up of such beams ?

Here it is:
