billboard

Austrian scientists have developed a new kind of 3D display designed especially for large-scale screens that doesn't require special glasses but, instead, sends beams of light directly to the viewers’ eyes via a laser and a sophisticated mirror system.

Earlier this year, Gizmag featured a concept that proposed using billboards as shelters for the homeless. The company behind Project Gregory suggested that income from advertising on the billboards could subsidize the shelters' running costs. It now hopes to build its first such shelters next year.

The Gregory Project concept aims to make billboards in the Republic of Slovakia into viable homes for the homeless.
