The idea of seeing two things at once is not new but the other day while walking in a garden we found a well fed garter snake laying in the sun. My son pointed out the snake had most likely found and eaten a fish that had washed up on the shore. It really looked that way. The image of the two existing together reminded me of the story The Little Prince by Antoine de Saint Exupery in which a snake is drawn after having a meal of an elephant.
Later that evening making a sketch of the event on the ipad came to mind. I was reminded of the sketching tool within note and set about making the sketch. So Maybe I am softening on the idea of sketching on a computer because the program however simple to the eye works very smoothly.
