It's freaky. With silver dollars duct-taped to his eyelids under a four-layer blindfold, mentalist Christopher Carter holds up cards submitted by audience members and shouts out their names and detailed personal information--childhood addresses, driver's license numbers. And this is his least astounding trick. Carter swears that his only tools are an acute awareness of body language and hyperdeveloped intuition. And as in previous shows, he shares anecdotes about his showmen predecessors, but he keeps these to a minimum, allowing time for ever more amazing feats of paranormal communication. Having participated twice in these mind games, I can testify that Carter is mind-blowing. Better still, his good humor, energy, and Barnum-esque charm engage and enthrall the audience throughout the 90-minute performance. Royal George Theatre Center, 1641 N. Halsted, 312-988-9000. Through August 1: Saturdays, 5 PM; Sundays, 7 PM. $25.
