This instructable will teach you how to make a wall mural fast and easy with an overhead projector. It's really not very difficult. You probably need to do this over a period of two days, but not too many hours are involved.
My family is into cycling, A LOT! We live next to the Minuteman Bikepath, the busiest bike path in the USA. We use part of our basement as our cyclery (or bike boudoir). And it looked like a dungeon down there!
So we decided to spruce up the basement with some floor paint, and a mural.
You need some stuff:
1) Some art - your own original or a poster perhaps
2) An overhead transparency projector - or a modern PC projector
3) Some paint (latex house paint is fine), you can scrounge from your paint stash or buy small inexpensive samples at the hardware store.
Step 1: Choose the art you want to use.
We saw this Nike poster in a cycling magazine and we thought it would be awesome! It's simple in design and colorful! We are not mural artists but we had heard of the technique of using an overhead projector. So we figured that the simpler the better.
