The Calypso contains three straight lines. The horizontal straight line is clearly visible, it passes through the origin (zero) where the upper and lower part meet. The two other straight lines lie in a vertical plane, they also pass through 0 and intersect each other at that point. The equation of the Calypso is a mathematical classic x^2+y^2z = z^2 and was suggested to use for the IMAGINARY exhibition by Herwig Hauser. The 3d-data was produced by Oliver Labs (www.MO-Labs.com) using data produced earlier by FORWISS. It can be downloaded at the IMAGINARY website.

Please note: IMAGINARY is an open source and non-commercial project. All 3d files are available under an open license, such that you can re-print the sculptures for own exhibitions (following the license specifications). To reimburse our "3D data expert", who takes care to polish and prepare the 3d data and to put the sculptures on the Shapeways shop, we added to this sculpture a 10% fee to the Shapeways price. This amount will be used only for work related to offering more 3d data and sculptures openly and freely to everyone. You can also print this sculpture from your own account.
