Here’s a fun way to teach children about how far cell phones have come since they were introduced in the ’80s: Russian nesting dolls. British designer Kyle Bean traces the evolution of cell phone design- and size- with a collection of nine ‘cell phone dolls’ in his piece Mobile Evolution.

The first, and largest, phone of the collection is the first commercially available cell phone, the DynaTAC, forever immortalized in pop culture (across several generations, no less) by Gordon Gekko in Wall Street and Zack Morris in Saved By The Bell. Bean traces other major milestones in cell phone history with the remaining 8 designs, ending with, of course, the ubiquitous iPhone.
