Projekt Rollendes Galerie [Project Rolling Gallery] was originated by Thomas Koch of Stuttgart Amerikahaus with the idea of taking art beyond the gallery walls by having Detroit artist Lowell Boileau create a MicroPointillist painting on a Stuttgart city bus. The project was supported by an Arts America grant, Stuttgart Strassenbahn, Daimler-Benz, and Academie Schloss Solitude.

The 25 x .6 meter (90 foot x 25 inch) painting was created during May and June 1992 at the SSB streetcar restoration facility in Vaihingen. The public splashdown occurred at the Schlossplatz of Stuttgart on June 5, 1992.

Entitled "The Gentle Chaos" [Sanftes Chaos], the seven panels of the painting are in a Chinese scroll painting style and picture a traffic gridlock of cows and cars. At one end birthing cars disgorge from a robotized factory. At the other end a 1950 Buick peacefully rusts away in a pasture while a lines of cars wind into the sunset.
