In back to back posts Rhizome.org notes two similar riffs on Paik's "zen movie" from the early '60s. Paik's film consisted of clear celluloid projecting a white image for its entire run time. The two contemporary riffers both do takes on the dust and scratches that inevitably accumulate on the film: one actual (a re-filming of an old Paik with much dust on it) and the other virtual (iMovie fake dust and scratches). File under art eating itself.
In the late '80s or early '90s there was a painting series being shown around that might be described as "Rymans with cracks." It wasn't officially couched that way but viewers were free to do so (among other possible interpretations). The crack-making process and tangible result intrigued more than any unpacking-the-famous-elders narrative.
We need to move on from these canonical artists from 35 years ago. There are interesting things happening right now that don't depend on a textbook avant gardist for sex appeal.
