Ingenious recipe holder

I always thought I should have a recipe holder to avoid spilling items all over my recipe cards or books. Well, not anymore. I saw this pic below on pintrist and would love to thank the brain who came up with it, but it won't link back to them. So....just enjoy the idea and enjoy saving the cost of having to re-print your recipes over and over because you spilled on them while cooking. Now if I could only figure out a good way to do this for my books.....
