You can make amazing kaleidoscopic patterns with the help of a keyboard shortcut. Cmd/Ctrl+Shift+Alt+T lets you duplicate a layer and repeat a transformation in one go. To demonstrate, we’ve made a narrow glowing shape by squeezing a lens flare effect, but you can use any shape, image or effect you like. First, make an initial rotation by pressing Cmd/Ctrl+T and turning slightly, then hit Enter to apply. Next, pressCmd/Ctrl+Shift+Alt+T repeatedly to create a pattern.
