Mary Heilmann: Looking at Pictures

I went to see the Mary Heilmann exhibition at the Whitechapel Gallery today. I loved the vibrant, playful colors, a sense of a certain measured carefree quality in her work.
I liked this quote from the Guardian's review of the exhibit:

"Paint drips accidentally, like when you get a bit of sauce on your nice clean shirt when you’re enjoying a meal too much. Entire paintings go over the edge and round the sides of the canvas stretcher, like those cartoon characters who run over a cliff and don’t fall until they recognise the drop below. It is good to sidle up to Heilmann’s paintings, to see what’s going on around the side, as much as it is to confront them head on....
Heilmann’s paintings aren’t the best in the world, but they don’t need to be. To me, they seem to contain a lot of happiness and pleasure in the act of looking. The human details and imperfections count. A hand and an all-too-human brain made them."
