Pixeleaters

I loved your drawing object trails video, it gave me an idea that might be something for your coding challenge series?

The idea is to add an image from a webcam to the canvas, and as the (ellipse) particles scramble across randomly they "sample" the pixels underneath. The brightest pixels in the selection are adjusted on step brighter (or more transparent), and the darkest pixels are adjusted on step darker. In short changing the image gradually, "cleaning it up" like bacteria seen in a microscope would eat sugar on a substrate. Not sure if that explanation made sense :)

Anyways, keep up your fantastic work, you have a unique way of explaining that and enthusing that I absolutely love.

The suggestion names no repository files, tests, or entry points, so begin by reviewing the project structure and deciding where webcam input, canvas rendering, and particle behavior belong. Done would require an agreed implementation scope and a working example that demonstrates the described image-cleaning effect.
