Ultra portable projector?

[75km]

I've been out of touch with technology lately- never been a T9 reader - but saw some half-sized lcd projectors in an electonic shop. So I just started thinking if theres a usb projector available yet that cuts out the need for rgb/fan/power components.Or if anybody's attempted to DIY projectors can they post details under this topic. Thanks

i try some utra portable one...
it's not ok yet.

stay classic, probably this will be ok in a couple of years, not today.

the most important is:
- ANSI
- screen size
- lamp price
- trapeze option.
