I stumbled on Tim Knowles’ artwork a few weeks ago and was thoroughly impressed by his unique mix of art/photography and scientific experimentation. Many of his projects take a very scientific approach in order to capture or create the artwork. For example, one project has him attaching pens to the branches of a weeping willow tree and placing a large canvas under the pens. As the wind blows the branches they scratch out their movements on the canvas, which Tim later shows at a gallery along with other similar works from other trees. Very creative!
