I just learned that Lewis Klahr, a filmmaker we like a lot (go here  and here ), has posted a 2009 film online. See Lethe here in its HD glory , accompanied by a program note by Tom Gunning.
But hurry! It’s being taken down on Friday.
Thanks to Lux Artists Moving Image  and Mousse magazine  for making this and other artworks available. And thanks to Madison Film Forum  for the link.
