I challenge thee to find a kid who doesn't like dinosaurs! Well, I'm joking, obviously, I bet quite few don't, or grow out of the dino phase very quickly (my sister was surprised to learn in the orphanage where she was working in Uganda thay nobody had any idea what these strange animals were...).
My eldest son Dylan was mad about dinosaurs for years, and would have absolutely adored design student Koichiro Hoshino's Casaurus, a dinosaur-themed bookshelf / playground, designed for his senior thesis at Tokyo University of Arts.
I really love this book tree, but I have to admit that a dinosaur bookcase that you can actually climb on, slide down and play inside with all your friends, well, wow, that looks FUN and sure must take some beating!
