I don't think he will answer positively. It's only a demo and somehow I don't see him releasing an unfinished program. But I can imagine other people picking up his ideas.
Actually there is someone in the Vimeo comment thread who has started a live canvas editor(1) inspired by one of the demos.
great link! geez, this reminds me why i like to use web developer tools so much when i'm adjusting my CSS, HTML, and JS. honestly, a lot of my ideas come from real time editing. i love making small adjustments to my values and getting to see those take effect instantly.
I can't believe the original link (submitted 5 days ago) has gotten so few views/points.
