The Second (and absolutely last and final) Supper
Patrick Lichty & Second Front

This tableau was created in the earliest days of Second Front, when Man Michinaga (Patrick Lichty) had built his first virtual studio in the Second Life area of Han Loso. As Second Front was getting ready to perform their piece, "Binge" for Art's Birthday 2007, Man built a tableau based on Da Vinci's "Last Supper" in the building on the floor below the performance area. The set consisted of a dais with turkeys, birthday cakes, and so on, and was backed by a 3D rendered simulation of Da Vinci's scene.

Shortly thereafter, all of Second Front (the first group dedicated to contemproary performance art in Second Life) showed up and sat at "the table". what is depicted here is one of three extant images and a frame from the video.

It exists as the mural you see here, a 2m oil painting, a 2m digital print, and a 3 minute video (mature audiences only).
