Built to give seven of his kinetic light works a permanent home, Christopher Bauder’s 1,000 square meter exhibition space DARK MATTER opens in Berlin. The career-spanning selection also includes Inverse, a choreography of 169 black spheres set against white light (image) the German artist created specifically for this space. “The artworks which have travelled the world over the last 20 years are now coming together in one exhibition in Berlin,” Bauder writes. “Never before have I had the opportunity to show so many of my installations in one place.”
