Rollup Printer

Not really a printer, but it's a sheet of something that you pull out, and, as you pull it out, the gadget writes to the LCDS on it to create a printout - and the thing is springloaded, so if you let it go, it'll roll back. Nice - you stick your USB drive into the car and pull this sheet out and it has the first picture/PDF displayed. You release and pull again, you advance to the next slide, etc.
