The Explay Nano Projector may not be the finest projector on the block but it does have the distinction of being the world’s smallest projector! The projector has been developed by the Israeli company Explay and it measures around 20 cc and 5 cm in length. This one uses a laser-based light source and thus is able to produce sharper and bright images ,despite its small size. If successful expect it to be a rage as Nanoprojectors can be embedded  cars ,passenger airliners as virtual displays for entertainment systems,mobile devices etc.
