When I was creating Act XIII & looking about Photoshop for butterflies [didn’t find them until after I used stars!], I found a tutorial to define my own shapes. I created a 6-pane window for my next Art Design course assignment & have it available now to distort in height & width.
This started out when I used the shape tool to create one, then another in a different size, then different proportions, . . . Next thing you know I have a “modern art” piece that I like:
I think I’ll come back to it later & play with other effects. I could have different scenes peeking through the windows. I might add a moon, etc.
