Screw Modifier Gems

We all know what the Screw Modifier is for. But after accidentally clicking on it while working on a model, and seeing what it did to an actual shape rather than a line, I decided to experiment with it. What I came up with were some interesting ‘gems’. I made some basic shapes, changed where the origin point was, and applied a screw modifier to each.
The blue was a cone; the purple was a cube; teal was a pyramid; and red, a heart.
