Invitation to Listen in a Van (for Wendy Carlos) (2019) is a tribute in the form of a social sculpture—with a clunker van, discography in “road case,” digital “mixtape,” blinking neon roof beacon, hi-fi sound system with subwoofer, screen print (ed. 50), and snack kit. The small i: "It represents the mathematical term for the imaginary number constant, defined as the square root of minus one, a concept that doesn't exist in the real world, but helps solve many equations...Math and physics people routinely refer to small i, the imaginary number. I must have picked that up from my days as a student at Brown University, when I shifted my focus, first in physics, and then in music and composition...The tiny i is located at the base of the transistor schematic, as this is the normal input for this minimal circuit component. It's all terribly clever, don't you see, that Tempi's music-notehead is a transistor, the main element of a Moog synthesizer, and it's located to amplify (are you ready?) imagination, symbolized by the imaginary number, i."  This project is for nonprofit educational purposes. With production help from Tim Bearse, Julia Gualtieri, Andrew Knox, and Kiri Miller.
