Did you have one of those wonderful kaleidoscope toys? Cardboard tubes filled with bits of colored plastic. Point it at the light and away with the fun. A bit of cheap joy. Though I wonder if they would be as cheap to buy now? Probably not. They seemed so ubiquitous when I was kid.
I loved how a quick flick of the wrist could change the colors and design. Each new combination just as beautiful as the last. Insta-art at its best. This Silk app reminded me of that.
