Does anyone know how to make an Overhead Projector?
Hi All, does anyone know how to make an OHP (just to be clear "OHP" not "OAP" - I already have a couple of these and despite their age they work perfectly well). i'm no artist (nor nuffink), but i'd like to paint an intricate image onto a large canvas. i've mocked the image up on paper, but to ensure accuracy, i'd like to project this image on to the canvas and trace from that. i'm unable to link my computer to an OHP device for all sorts of dull reasons (that neither you, nor i would want to go into right now), so unfortunately this isnt an option. all (practical) ideas will be gratefully received. regards Rens
