Just like an iPhone crams a roomful of devices into a pocketable device, miniaturization of electronics has now made it possible to create a battery-powered, cube-shaped pico projector just 1.8 inches (4.5 cm) on a side. From an unexpected source -- South Korean mobile provider SK Telecom -- the device is being marketed as the Innoio Innocube.

Design
SK Smart Beam Art is a premium colored pico beam projector sized 4.6cm weighed 130g cube reduced significantly heat and noise, which enables mirroring of app contents, movies, internet, DMB, photo,video images as well as video calls.
 
It supports not only smartphones but also all HDMI supported devices.  Maximum 90 inches at 3 meters distance screen wide is possible to project from this light and small cube.  The Brightness of 40 ANSI Lumens that can be possible to use days as well as nights.  It can make your home to a theater or your office to a seminar room for presentation.  You can project e-book or movie to ceiling for your kids before you sleep simply or even outdoors when you go camping it's very convenient and portable.  Smart Beam is compatibly setting with Samsung Galaxy S2, S3, S4, Note and Note2, HTC Radar 4G, Sensation and Motorola Razr.  For Samsung Galaxy Tap 7.7, 8.9, 10.1 and Apple iPhone 4S, 6, iPad 2,3,4, iPad Mini, iMac, Macbook need separately its own AV adopter and HDML cable.  A tripod and Clip only for Smart Beam is provided.  For Apple iPhone and iPad are not supported mirroring function and sound control  but used for moving images.

Innoio has added a rubberized bumper and backing to the unit to protect it from bumps and falls, which is smart considering that the target audience for the device is ... kids.  Yep, let the kids take the projector and an iPad into a darkened room, and they can begin showing movies or displaying artwork on any wall or ceiling.  

What's driving the pico projector is a miniscule Texas Instruments DLP chip containing millions of micromirrors.  TI and Innoio provided a few sample chips, and it's amazing what those diminutive circuits can produce.

Conclusion:
If you or your kids have a need for a tiny and impressively bright projector, the Innoio Innocube should definitely be on your list of projectors to check out.  

For presentations on the road by the parents of those kids, however, this would be a great portable projector for use in small, dark conference rooms where it can truly shine.

Incredibly lightweight and small.
Image quality and brightness was surprisingly good for a pico projector.
Can be used with HDMI-equipped MacBook Pros right out of the box.
Good battery life and fast charging time.
Pricing is in line with that of other pico projectors.
