ghost lines

Today's prompts: use lines wisely (I used them unwisely), self-portrait, look deep into the void. What I did:

• sampled a webcam stream in greyscale
• found the frame's center of "mass" (where black=hi, white=lo)
• randomly sampled a subset of the points that changed values between sample frames by over a nontrivial threshold
• drew vectors of the change in overall frame center of mass from those points

(Not implemented on mobile yet.)
