The Worm happened accidently when I was programming for my GSoC 2015 participation. In my GSoC project, the dots represented patients and patient pairs with similar genomic profiles attracted each other, while different patients where repulsive.
For the layout I implemented the Force2-Atlas algorithm that is used in Gephi in JavaScript. At some point I introduced a bug, where the patients formed a linear chain which resulted in this worm creature. You can controll the blue ball with W,A,S,D.
The worm tries to catch the blue ball. You can also just watch the dots assemble at the center of canvas.
