This example shows you how to use a GUI to interact dynamically with sketch parameters. It also includes the use of listeners to check for changes.

When you open the app, you should see a screen with a hexagon and a number of sliders. Click and move the sliders to change the hexagon.

Try changing the circle res slider to create a circle. Try clicking the fill toggle.

Pressing the h key will hide and show the panel; spacebar sets color to white.
