Lush climate - the lighting/illumination on the bamboo is flashing/strobing. Never seen this before, but might need an epilepsy warning. Current weather is dark and snowing (early am time). Don't have the correct tools to install to get a video of the effect, sorry. Basically, the bamboo is rotating between these two images.
