Bringing meticulously constructed film sets into the white cube, Bob Demper’s “In Tall Buildings” opens at 1646 in The Hague. The Dutch artist presents several scenes—a bland boardroom, a marble-adorned lobby—and excerpts from 5000 Miles, his ongoing feature film project about an asset manager that (algorithmically) controls 10% of the world’s wealth. Inviting visitors to contemplate the seat(s) of power, Demper illustrates “how the risk taken by the corporate world is almost always a public risk.”
