I made these, but you need to see them in person to see how they work. They gave me an idea for a cool and very cheap way of doing publicity for another show in the favour.

You can only tell what the image is if you stand 10m back, but then you'd have to walk right up to them to see what the accompaning text says. And because they be done via photocopying, you have heaps of different versions to keep the punters interested.

squinting helps too...
