An experiment with using bend to create an interesting shape. In this case a simple rectangle bent by a circle. The key was to first resample the rectangle, to ensure the bend has enough points to work with. Then also to use enough steps in the circle to make the result smooth. Then I applied a Kaleidoscope transform to create a pattern with them and applied a colour gradient across the pens for a nice shading effect.
