Nice hunt @lonelyboy!

The 'HD Pico Projector' claims to be the world's tiniest 720p projector, which is likely to be true as it only measures 2.3x2.3x2.3 inches and only weighs 6oz.

It has an internal battery which will keep you going for up to 1 hour and 50 minutes. That's plenty long enough to play most full length movies.

The LED lamp lasts up to 20,000 hours. That is about 8 hours use, per day for seven years before it needs replacement.

Connectivity is good too, as it has HDMI, A/V, USB, headphones connectors as well as a Micro SD slot.

This looks like a product of which I would love to try!
