Artist Dorothy Tanner uses light as her medium — along with water, plastic, fabric and her imagination. The sculptures adorning the walls and fountains on display at Lumonics are psychedelic and mesmerizing. When Tanner and her talented crew open up Lumonics for an event (which is at least every weekend), there's almost always a light show filling an entire wall, courtesy of guest videographers and designers or the Lumonics experts themselves. The space contains several rooms and display areas, with secure spots to stash coats, shoes and jaw-dropping art (don't miss the pyramid installation). Shows range from intimate world-music journeys to bass-heavy dubstep lineups to DJ workshops to ecstatic chant and dance. For an illuminating experience, there's no substitute for Lumonics.
