My wife just sent me a wonderful tribute to Bob Ross by Korean artist Kim Beom.
The work is discussed at The Walker Art Center Blog.
Update: As you can see the original video is gone. It was only available for a limited time for some reason. I wouldn't doubt that a search for Kim Beom and Yellow Scream will bring up something. Just be sure to note that there are edited down versions out there that don't really capture all of the wonderful humor of the original and focus more on the screaming, which is entertaining enough but not the full experience.
I had a hard time finding more information out about Kim Beom, partially due to a name collision with a famous Korean actor. I did find another article describing a recent exhibition called Animalia at REDCAT. There are various reviews of the exhibition online as well.
Another video, from Animalia, is Horse Riding Horse (After Eadweard Muybridge).
To explain what may seem to many to be a random series of consonants and vowels following the word "after" above, Eadweard Muybridge was an English photographer. According to Wikipedia:
Muybridge is known for his pioneering work on animal locomotion in 1877 and 1878, which used multiple cameras to capture motion in stop-action photographs, and his zoopraxiscope, a device for projecting motion pictures that pre-dated the flexible perforated film strip used in cinematography.
It is good that everyone know the pioneering inventor of the zoopraxiscope and that his name is never forgotten. Seriously, this sounds like one of those major innovations that people tend to forget. Instead of remembering assholes like Steve Jobs, famous for becoming rich, let's drill the name of a true innovator and inventor into our permanent memory. So repeat after me "Muybridge invented the zoopraxiscope. Muybridge invented the zoopraxiscope. Muybridge invented the zoopraxiscope. Muybridge invented the zoopraxiscope. Muybridge invented the zoopraxiscope. Muybridge invented the zoopraxiscope..."
