Sunbeam Geometry

Existing in three dimensions is fine, but flat shadows seem much easier to mess with. Right around mid-morning, a sharp rectangle of sunlight landed across the painted wooden window sill, cutting the room into bright and dim halves. I hopped up next to a clear glass prism paperweight sitting by the frame. Instead of just admiring the view outside, I tilted the heavy glass block flat onto its corner using both yellow paws. Suddenly, a streak of warped rainbow split across the wall, cutting directly through an unsuspecting houseplant leaf. I call that successfully deconstructing the sun.
