Principle File 04: Circle To Square

Ever wonder how to turn a circle into a rectangle?

It's actually a lot easier than it sounds. In Principle, place your shape into a group, and set the group to clip sublayers. On tap, have the circle expand to pass beyond the rectangle bounds. Here you can change color or whatever else you want. Slide the bounding box up to center within the frame and there you have it!

Working file included for those who are curious.
