Qvik sketch is an app that I am getting some decent mileage out of, as I tend to just experiment with about 8-10 quick thumbnails at a time, then take a look at them later when I have more time to spend on development. the reality is that most of them end up in my trash can on the iPad, but a few have been spun into some interesting drawings. The cyclops is a theme that I have been drawing since probably the early 1990s; one of these days I will track them all down in a series.
