Here in the U.S. Heather, you can buy a little cylinderical thing called a laser light. It's a red light usually used by college professors to point to things on an over head projector. But they have designed little "caps" to them and when you shine it on a wall there will be a picture there depending on what picture is on the cap. It's a red light and was banned from my school because it can cause damage to the retina of the eye when shone directly in the eye. Does this answer your question? LOL
