It’s a fascinating technique. You can see the relation to someone like Jackson Pollock, in that he’s reacting to the placement of previous layers on the surface & making immediate judgements as to where and what to paint next. The results are really interesting in & of themselves, but for me the real fascination lies in the process. Those animations give you a real feel for how he works & the moving artworks themselves are what makes the work truly psychedlic. This is a difficult technique to get right: one false move & all you’d have is a big grey mess.
