I’ve seen this done several times over the years, including 1 or 2 by a fellow club member who is also actively embroiled in the 365 challenge. Time to give it a shot.
I googled “textures & patterns” and borrowed a few likely candidates for my personal use (note the disclaimer).
I then blew them up to fit the screen I am using, put 2 glasses filled with water in front of the screen & moved them around to get some interesting refractions. Different textures produced some interesting results.
Today’s challenge included selecting a “best of”, but this guy won out.
