Such was the rallying cry of Wayne Hoffman, the world-renowned illusionist and mentalist who performed in a free show at the Massey Performing Arts Center Wednesday night. Hoffman, who has been featured on every major cable and network TV channel, specializes in what he calls mind candy–gathering basic information about people, including their dress, posture and accent, to be able to formulate an idea of what they are probably thinking. In essence, Hoffman reads their minds.
