The Optoma Pico is one of the smallest projectors available in the market. Manufactured to be used with an iPod, the projector can also be used with an iPhone. The Pico is very light, weighing in at just 120 grams. The pico can project a 480×320 resolution image on almost any surface, between 8 inches and 8 feet away. The projection is pretty bright for such a small device (9 lumens). Available for only $430 (Rs. 21,256), but the device will burn out after 20,000 hours of usage.
