This project is about developing a set of 2D GUI components including buttons (image and/or text), sliders, knobs, labels, textfields, timers, combo boxes, option buttons etc that can be used with all 2D and 3D graphics modes in the Processing sketching environment. V1.4 added the ability to have multiple windows for input/output controls and drawings.
