Beautiful work.

The full panel approach reminds me a bit of some interface work shared by @ITman496 on the old forum for RPi3/ RPi4. Different designs, obviously, but in a similar spirit.

> There are several approaches to this problem. Some include: draw many tiny arc segments to create a gradient (solution from @Ov3rM1nD above) create a closed PShape in the shape of an arc and fill with a gradient (e.g. a PShader) draw a full gradient image, then draw a single arc as a mask and apply to “cut-out” your gradient. For examples and past discussion of the mask-based approach, see: [https://forum.processing.org/two/discussion/20005/2d-gui-libraries](https://forum.processing.org/two/discussion/20005/2d-gui-libraries)[https://forum.processing…](https://forum.processing.org/two/discussion/18818/how-to-draw-a-transparent-pgraphics-image-solved)
