The Phaeno Science Center in Wolfsburg, Germany has commissioned a permanent installation of Sisyphus. This version will be 3 meters in diameter. Because of a tight timeframe, the "furniture" (structure that supports the mechanism and sand field) will be fabricated in Germany using my CAD files, while I build the mechanism and electronics at the NEM makerspace in Minneapolis. We leave for Germany the last week of September.
