Relaxed evening viewing film on ceiling

Ok, I know that there is a wide community building DIY beamers using screens and overhead projectors (or even custom ordered sets of Fresnel lenses).. but that does not prevent me from putting my own together.. in less than 10 minutes (the time it took to remove the top mirror of the overhead – the tft monitor had been disassembled previously)

requirements

Overhead projector, ventilator, 15” tft (with defective backlight or inverter, so completely taken apart), laptop or other VGA source 🙂
