When I'm putting some communication out on Twitter or Facebook or Instagram, I think that it's helping me, my brain, you know, because it's always somehow stimulated by people who are sending things to me. And it works both ways. It's great. My brain is very happy about it.
I always believed that my work should be unfinished in the sense that I encourage people to add their creativity to it, either conceptually or physically. Back in the 1960s, I was calling for 'Unfinished Music,' number one, and number two, with my artwork - I was taking unfinished work into the gallery. And that's how I was looking at it.
