Just saw the David Hockney show and remembered some drawings I sketched on my iphone when the app Brushes came out. It was fun to do, like, when you are waiting in line or you have some time on your hands – just take out your cell phone , or ipad and draw with your fingers or your thumb. Hockney draws with his thumbs. Thumbs have more range of movement than fingers so he has more options when drawing, than if he used his fingers. To all my American friends, on this Thanksgiving Day, Happy Turkey Day. Thank you for checking in sometimes.
