One of the coolest exhibits of dioramas since the Joseph Cornell boxes at the Art Institute, the Glessner House features tiny crime scenes made by none other than Frances Glessner Lee, the daughter of the notable Chicago family. The exhibit, titled The Nutshell Studies of Unexplained Death contains scenes, replicated in 1:12th scale, complete with tiny shell casings, bloodstains, and real movable parts. Intended for instruction on forensics and proper investigation techniques, these were no morbid fascination, but instead were a valuable teaching tool for 1940s and 1950s police.
