I snapped this picture. Not a sharp image, but I did capture the shapes and colors.
Then I played around with the image in photoshop, trying out different adjustments and filters. I'm not sure why it's so much fun manipulating photos. Maybe the element of surprise, and the chance to experiment with colors without having to clean up big messes.
These last two are abstracted quite a bit and barely look like palms anymore. But I think they still the have the essence.
