Same as the code in springs, but the controller has been updated:

• loop starts and stops with "l" instead of UP_ARROW
• remove the need to have the runFlag in the draw loop
• to generate a recording burst on button press "r" if recording is enabled
• will save on "s" press if gallery mode is disabled.

Instructions

Click on the disk and drag it around.

• "l" to start or stop the the running sketch
• "s" to save a single frame
• "r" to record a burst of frames.
