Sometime around 1918 in Buenos Aires, Marcel Duchamp designed a chess set:

Sometime earlier this year, Scott Kildall and Brian Sera used archival photos of the hard-to-find set, turned them into 3D models of the chess pieces, and made a pattern for 3D printing your own set:

The community at Thingaverse is already busy making interesting variations of Duchamp’s set…look at this one:

Something tells me Duchamp would have loved this whole thing.

Update: Welllllll, Duchamp may have loved this, but his estate definitely did not. Duchamp’s estate sent Kildall and Sera a cease and desist letter, forcing them to remove the 3D models from Thingiverse. Which, the irony! So, Kildall and Sera, riffing on Duchamp’s mustachioed Mona Lisa, have created a set of six 3D-printed chess pieces with mustaches modeled on the Duchamp set. Fantastic.
