Gabe Fonesca, a professional TV writer, understands the importance of breakfast cereal. His YouTube channel is an exhaustive exploration of the sugary glories of our childhoods. His home, appropriately, features a wall that is covered with box after box of classic and obscure cereals, including Smurf Magic Berries and Pink Panther Flakes. You can see more photos of this wonder here.
Fonesca made it by attaching thin sheets of steel to the wall. Tiny magnets hold the boxes in place, so he can adjust and re-arrange them with just a little pressure.
