Jagger Smith, age 12, builds a house as tall as he is using the Cocoro playhouse system, showcased at the Maker Faire in the University Library on Friday, May 10, 2015. The Cocoro playhouse, which uses lightweight but durable cardboard that can be stacked and combined for limitless possibilities, was created by NorioKids, who’s founder got the idea from playing with legos and lincoln logs as a kid and always wanting to be able to fit inside.
