Solid Poetry is the graduate project of Susanne Happle and Frederik Molenschot of The Netherlands' Design Academy. It is a design for concrete tiles that reveal a hidden pattern when wet. The idea behind the project is that weather, especially rain, already changes the look and feel materials. Why not utilize this natural process to add beauty and style.
I think this project is so brilliant. It takes the negative of a rainy day and turns it into something positive to look forward to. The Solid Poetry also utilizes one of my favorite design ideas, a hidden delighter. Something that you don't see right away or isn't apparent in regular use but reveals itself as a pleasant surprise later on. This reminds me of my very first post on this blog, the Stamp Mugs.
