Sha Hwang has created a bookmarklet that you can add to your browser and use it to slitscan any Youtube or Vimeo video! Just drag this link to your bookmark bar: slitscanner. Then open a video in Vimeo (make sure you are using HTML5) and click on the bookmarklet. SO COOOL.
I created the above image using this Lazer Sword video (this is also the example Sha uses on his site). Sha says users can download the code and modify it. He’s publishing slitscans to: shahwang.tumblr.com
