From 1921-1927 Oskar Fischinger experimented with melted wax and animation and created his “Wachsexperimente” film in 1927. The process, as explained by his widow, Elfriede:
“[Elfriede Fischinger] explained to me that Oskar would fill a bathtub with paraffin and swirl oil colors into the hot wax and let them solidify. Then he would place the solid block of wax on a table where he had built a machine that would thinly slice an end, like slicing baloney, and then a camera he had mounted at the end would shoot one frame of the swirls; then repeat this a few thousand times, and when played back at 24 frames it moved in pleasing patterns.”John J.

The film is accompanied by an excerpt of “Construction No. 4” by Noiseman433 (Jon Silpayamanant), track 4 of the “In Memoriam John Cage” album which was released in 2003 on Danish label “Legion Sudan” (LS.433).
