The cover photo of Stagelight, the playbill for Mindplay, shows Vinny DePonto, its star (and co-writer, with Josh Koenigsberg) with a swarthy, tight-lipped, foreboding visage. He might easily have just emerged from a coffin in Transylvania, but, thankfully, on stage DePonto is engaging, earnest and unthreatening. In explaining the raison d’être of his show, he mentions his own anxieties, including being subject to panic attacks. “Your mind takes over your body if you’re one of those people,” he says. “I’m one of those people.”
