In a previous life, Luigi Anzivino earned a Ph.D. in neuroscience, researching the brain's reward and attentional mechanisms. Currently, he designs, builds and facilitates hands-on "playful and inventive explorations" at the Exploratorium, San Francisco's museum of art, science and human perception. The infamous "magic bug" bit him when he started working at the Exploratorium and, in addition to compelling him to spend hours fiddling with cards in his spare time, it has provided him with an excuse to apply his hard-earned scientific knowledge to a subject he loves.
