The Laughing Man is the antagonist from the anime series Ghost in the Shell: Stand Alone Complex. During each of his public appearances in the series he manages to hack all video feeds/cyborg eyes in the vicinity to obscure his face with the logo above.

[Ben Kurtz] had been watching the series recently and realized he could put together a similar effect using Processing. The interesting bit, and what makes this more fun than a simple demo, is that he’s using the OpenCV library. OpenCV is a open source computer vision library. [Ben] uses it to handle the facial recognition in Processing and then apply the image.

It’s only 100 lines and we wonder what other fun tricks could be employed. Here’s a Hack a Day skull you can swap in for the logo.
