Grok 4.7 oscilloscope drawing demo goes viral, author open-sources clean 192kHz WAV

A demo using Grok 4.7 to generate a stereo WAV that draws a picture on an oscilloscope is making the rounds: left channel drives X, right channel drives Y, so playing the file traces the image.

The author notes X compresses audio in videos and loses part of the signal, blurring the picture, so the clean 192kHz/24-bit, 33-second WAV is open-sourced on GitHub. Anyone can replay it on the free online oscilloscope at dood.al/oscilloscope.
