The VAG Ian Wallace exhibition is astoundingly boring, but apparently he was on about the "intersection of painting and photography" which I don't really believe applies to putting a big photograph near a rectangle of colour. But what do I know.
The obvious problem there, labourwise, is that you have to do two things: take the photo and paint the painting. Video, however, will do your paint-swipes for you if your subject is in motion or you have a sufficiently palsied hand.
Voila! A pulse to wipe the slate clean at intervals offset to the loop of the video and you have as many paintings as frames in the loop, which, if you let this run in Quartz Composer or as a screensaver, is about 1865 possible paintings (one of which might be good!) and thus close to two million equivalent words, making me a prolific writer in the bargain. Take that, Wallace!
Sound by robots because they work cheap.
