This pocket-friendly device, no more than 12.5cm (4.9in.) in length, features a built-in stereo speaker and it is capable of projecting a 50 inches wide image onto your wall.

Powered by a rechargeable lithium battery, the Pocket Cinema uses a high powered LED to fling images wallwards (yes, we made that word up). We’re not talking plasma quality – and like all projectors image quality diminishes with distance – but dim the lights and it’s just like being at the flicks.

As well as its ability to free the pics and vids in virtually any device, the Pocket Cinema can also play directly from its 1GB internal memory or built-in card reader. Simply pop in a card and Barry Norman’s your uncle. We’ll even chuck in a remote control.

The Pocket Cinema is available from Firebox.com for £299.95 (about $523 USD).

Once inside, they can watch a movie complete with 7.1 surround sound. After one show ends, though, the homeowners can press a button for another show to begin—the 180-degree rotation of the floor, creating a more intimate living room atmosphere.

Here’s a time-lapse video of the construction:
