Sisyphus in Germany

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.
