Thanks to the community transcription efforts [1], I can now say it is indeed a LOGO program that draws the actual comic [2] featuring Bob Ross with various things drawn in a whiteboard. Comments are identified as various turtle facts.
> It appears to be coding instructions, probably to draw a turtle, such as the image hidden on the page. This has not been confirmed.
The main object on the picture is a turtle. The turtle is a key concept in LOGO, a programming language especially designed to teach programming to children in an easy way.
And a link to a GitHub user who has transcribed the first 60 minutes of the audio into logo (pen up, pen down etc) and has drawn this image so far.
