Today I attended an art class run by Goldster. We were meant to draw a picture of Table Mountain from a photograph. I did a value sketch, however, as a basis for a painting. I know I will never paint it, but the experience was good.
I really could recommend Goldster, no matter what age you are. They have all manner of classes (meditation, tai chi, exercises, Indian cooking, and many more). They also have a free 30 day trial.
