This video shows continuous variation in angle (from 0 to Pi) of the connect-the-dots algorithm while keeping all other parameters fixed. Each instant is a valid 2-coloring.

Drawing programs don’t always have a “point”, even if they are fun. Recursive Drawing, however, aims to use a simple and addictive user-interface to explore how drawings could be translated into programming.
On the surface, it’s a purely fun tool (which you can, and should, play with!) to draw crazy-awesome things like Fibonacci trees (like in the video). But deep down, it’s an experiment in translating visual objects into programming commands. That’s called a spatial or visual programming environment, and it’s a way to disconnect the syntax of programming from the logic and math.
Environments like these also let non-English speakers and young people get introduced to programming skills without having to master the language itself. But if you don’t want to pay attention to all that, it’s just really FUN!

The secret lives of invisible magnetic fields are revealed as chaotic ever-changing geometries . All action takes place around NASA’s Space Sciences Laboratories, UC Berkeley, to recordings of space scientists describing their discoveries . Actual VLF audio recordings control the evolution of the fields as they delve into our inaudible surroundings, revealing recurrent ‘whistlers’ produced by fleeting electrons . Are we observing a series of scientific experiments, the universe in flux, or a documentary of a fictional world?.(via Magnetic Movie)
This video, by Semiconductor, is an artistic rendering exemplifying the dynamics of electromagnetic phenomenon happening around us and through out the universe. The animations are set to audio from VLF radio-wave recordings produced from real ambient sources such as weather systems, electrical storms, the Earth’s core, the upper atmosphere, and solar wind traveling to us all the way from the Sun.

An arbitrary point P on a torus (not lying in the xy-plane) can have four circles drawn through it. The first circle is in the plane of the torus and the second is perpendicular to it. The third and fourth circles are called Villarceau circles.
The set of all possible motions of a universal quantum computer includes accurate images of all possible motions of all physical objects. That the laws of physics permit this ‘universal object’ is clearly a profound feature of them, but still an elusive and controversial one.
This is a link to a video where David Deutsch talks about the universality of quantum computation, which is the property that a certain quantum computer can simulate any other quantum computer.
In this video, colors are assigned according to the directions and speeds of the points.
