I have no idea if there will be any FFC issues, but it might be a cheap way to build a decent resolution, small DIY projector.

Help Your Monitor Help Itself
Looking for that extra bit of screen real estate to get you through the busy workday? Referring to notes while writing an e-mail, checking info in a spreadsheet while entering data into a web page, keeping an eye on your to-do list while browsing YouTube... it's handy to have additional monitor space at the ready. Problem is an entire secondary monitor comes with its own needs like requiring a separate power cord or perhaps an additional video card.
The Mimo Mini USB Monitor changes this equation completely by offering a low-maintenance relationship between you and an extra display. A single USB connection from your computer gets you an instant high-resolution secondary display. This awesome display is perfect for your IM client, widgets, PC gaming tools, your email, a spreadsheet, your PhotoShop tools, or even video! Not only do these displays enhance productivity, they look great! The single USB connection, combined with a weight of only 1.3 pounds, means the Mimo monitor is ultra portable and cost-effective, as no expensive extra video cards are required.

Heck, I might buy one of these, myself, and build a smaller projector using some 180mm or 200mm fresnels with a matching triplet.
