Pop as many bubbles as you can in this amazing processing sketch.

I am trying my hand at some really primitive motion detection. Here is the basic process:

• Subtract the color values of the current frame from the last frame.
• Convert the result to grayscale.
• Blur that juuuust a little.
• Apply a threshold, reducing the image colors to black or white.

When all is said and done the white areas of the image represent motion.

Yes. It's a Processing sketch.
