The Phenomenon Of “Crown Shyness” Where Trees Avoid Touching

3 Comments and 5 Shares

Photo © Dag Peak. San Martin, Buenos Aires.

Crown shyness is a naturally occurring phenomenon in some tree species where the upper most branches in a forest canopy avoid touching one another. The visual effect is striking as it creates clearly defined borders akin to cracks or rivers in the sky when viewed from below. Although the phenomenon was first observed in the 1920s, scientists have yet to reach a consensus on what causes it. According to Wikipedia it might simply be caused by the trees rubbing against one another, although signs also point to more active causes such as a preventative measure against shading (optimizing light exposure for photosynthesis) or even as a deterrent for the spread of harmful insects.

I love this -- some trees grow to avoid contact in their canopy, called crown shyness.

Hey @Jack, hate Tweets are a real problem.

WoodSwimmer: A New Stop-Motion Short Made Entirely by Tediously Cutting Through Wood

1 Comment and 2 Shares

WoodSwimmer is a new short film by engineer and stop-motion animator Brett Foxwell, who has built armatures for films such as Boxtrolls and Star Wars: The Force Awakens. Created in collaboration with musician and animator bedtimes, the work follows a piece of raw wood through a milling machine, capturing its unique growth rings, knots, and weathered spots through a series of cross-sectional photographic scans. Due the speed at which the images are animated, the log’s grains begin to flow like granules of sand—shifting, mixing, and flowing in a vibrant dance that seems completely removed from its rigid material.

“Fascinated with the shapes and textures found in both newly-cut and long-dead pieces of wood, I envisioned a world composed entirely of these forms,” Foxwell told Colossal. “As I began to engage with the material, I conceived a method using a milling machine and an animation camera setup to scan through a wood sample photographically and capture its entire structure. Although a difficult and tedious technique to refine, it yielded gorgeous imagery at once abstract and very real. Between the twisting growth rings, swirling rays, knot holes, termites and rot, I found there is a lot going on inside of wood.”

Heads up: watching this full-screen in HD with sound makes all the difference. You can see more of Foxwell’s works, like his 19-minute film Fabricated, on his Vimeo.
