Show HN: Post processing a html page with webgl

I recently discovered html2canvas (awesome but I wish it was 1.0) and used it with webgl to re-render my web page.

Click on the image (Awolnation) and wait a few seconds (it might take some time to buffer audio)

Basically it takes ss of current visible part of html page, creates an empty canvas covering the screen and then renders that ss with post processing.

edit: there is a music so might not be work safe if you are using speakers
