Masked figures silently frolicked through the quad Tuesday morning in a silent performance for perplexed onlookers. The masqueraders are students in assistant professor Nick Erickson’s stage movement class, practicing the skills of silent acting. Erickson said the performance was like a midterm, allowing students to express all they had learned in the class which focuses on the importance of movement, body language and non-verbal acting in stage production. The exercise began with the students clustering in the middle of the quad for a choreographed routine which steadily evolved into full improvisation.
