A vast expanse of Venetian glass lamps greets visitors at the Mori Building Digital Art Museum: Epson teamLab Borderless in Tokyo. The lamps shine brightly when visitors approach, causing other lamps nearby to illuminate with the same color. Titled "Forest of Resonating Lamps - One Stroke," the exhibit is the work of teamLab Inc., a Tokyo-based group of about 400 artists and scientists. The museum opens on June 21.
