One of the more popular exhibits at Tokyo Make Meeting this past weekend was Mommy Tummy, a pregnancy experience simulation system developed by Kosaka Laboratory of Kanazawa Technical College. It allows men (and others who have never carried a child) to not just feel what it's like to be pregnant, but to also gradually experience the changes. The Mommy Tummy suit is pumped full of water, and the onscreen display updates you as to how far along your pregnancy has progressed. The man's breasts will get bigger as well – did I just write that? – via a pair of inflatable balloons on the front.
