It's somebody's project, not a cat video.
If you're willing to think about it for a little while, there's much beyond shallow interest.
Snarky answer: Would you consider toy railroads relevant to hackers? http://en.wikipedia.org/wiki/Tech_Model_Railroad_Club
It's hilarious how while it's writing it looks like two small arms cupping the marker. Slap on a smiley-face sticker and you're ready to go to market.

I was thinking the same thing. I envisioned a Muppet head and arms would do the trick.
EDIT: Just saw the super interesting comment bellow linking to a reddit thread where it calculates the theoretical values of ink usage.
If you own a 3D printer, there is a model up on http://www.thingiverse.com/thing:248009.
We want to make ones that sit vertically on our actual whiteboards and run off more permanent power-supplies.

But this of mechanic is certainly unique and adds a lot of clumsy robot charm.
Wonder how easily you could store human inputs with a kind of (reverse) Pantograph type device for reproduction.
I am currently building a whiteboard plotter myself, though a much larger scale.
Feel free to send me questions and I can send you pointers on where to research next.
I'm working a new version of my mobile testing robot that looks very similar to this clock. Haven't posted the code, yet, but I did have to go back and re-learn some trig and circle geometry to make the simulator. http://youtu.be/qRzrm4zx82g
You could probably build a similar thing almost out of the box (BYO marker and whiteboard) and you can replace the various parts with your own bits as you get more advanced.
I suppose if you knew what you were doing going an Arduino is a cheaper option though.
I liked the erasing style. Bit clumsy like a toddler.
I've made one that describes the process, if you are interested: http://goo.gl/Ykq88g
Could eventually be extended to scetch outlines of objects/people :D
I hope it was duct tape, otherwise it may not last for too long. Funny project, done in a cool way, and a great hack.
