John Johnston has a Raspberry Pi collecting skies for him. Not all of us have that luxury but we can all take a Pi Sky for inspiration. Take a photo of your sky today. Extra internet points for a gif, of course!

My Pi is no longer taking photo every 15 minutes, but I still love how the sky here changes. This photo combines two taken 6 minutes apart:

montage of two photos combined vertically. Both show a raven flying. The top over blue sky the lower uniform grey clouds.
