Many art installations worldwide have a “look but don’t touch” policy, but some art forms engage multiple senses, like a sculptural instrument that involves touching and hearing. Inner Waves by Artur Weber consists of glowing drums filled with water, prompting viewers to reach inside for a mesmerizing audiovisual experience. The drums look unusual, resembling a random drum set, and have a faint glow contrasting with the darkness inside. Plunging a hand inside reveals a brighter light and ethereal sound, linking the water inside the viewer’s body with that in the drums. This unique instrument likely uses vibrations from ripples to intensify light and produce sound, creating a meditative and contemplative experience.
