Ingo Gerken, "The Inner and the Outer Condition," 2009: “Ingo is an artist from Berlin and one of the most talented people I’ve met. He does quirky pen drawings, so I asked if he wanted to send me one. Then in the mail I get this pen and thermometer — he’d found a really nice connection between the two objects. The thermometer is a little smaller than the pen, so they’re not identical, but close enough. And the ink and thermometer level are about the same at room temperature. It comes with hand-drawn instructions showing how to install it: Just tape it to the wall with clear Scotch tape.”
