"[I]t’s partly because, in order to be creative, sometimes you need to consider some ideas that don’t necessarily feel like they’re on track with what you're trying to achieve. And so having all these ideas come into your mind because you’re not quite as good at putting them off when you're tired can actually make you more creative."
Original Title: Le feu follet
Movie director: Louis Malle
Life has become unbearably painful for Alain who is in his early 30s. He once used alcohol to dull the pain. His estranged wife in New York has paid for a cure at a clinic in Versailles and sends an emissary, one of the many woman he has known, to see how Alain is. She sees only the surface as does his doctor, who says it's time for Alain to leave the clinic. He goes to Paris the next morning to try to find the answer to his existence; will he?
Of course the prism is just glass (or some transparent material). It sits on a triangular base and has rectangular sides. In school I imagined it was some special material !
Refraction and speed of light in materials : Refraction simply means that light travels at a different speed in different materials. It's fast in air, and slower in water or glass. This has the effect of changing the direction of light, or bending it, when it moves from one material to the other.
But why do different colors go in different directions? This is because different colors of light travel at different speeds in the glass. So from the analogy above, slower speeds in the glass make the light bend more. We call this effect dispersion, since it disperses the colors in different directions. Blue light travels slightly slower in glass than red light, so it bends a sharper angle when it enters the glass from air. In physics, we say the glass has a higher refractive index for blue light than red light. There is a formula (Snell's Law) that you can use to calculate angles from refractive index, or the other way around.
How refraction actually works (Quantum Electrodynamics) : Another way to answer this is through QED which talks about how light interacts with atoms of the material it is traversing. I will not even attempt to explain this here. But Richard Feynman got a nobel prize in Physics explaining the phenomenon. See Richard Feynman Lecture on Quantum Electrodynamics: QED. 1/8 . You can even get his book and read about it.

"Build the Cities is a code-based generative music video I directed and programmed for the track Build the Cities by Karma Fields Feat. Kerli Kõiv."
"The entire music video consists of multiple stages. The basic structure for each stage is a dynamic subdivided cubic cell, which is able to multiply based on a designated distribution pattern.
For generating the animated singing figure (Kerli), the pattern is computed based on depth sequence of the original footage. Speaking of the footage, a Kinect, a camera, plus Depthkit (depthkit.tv/) were used to shoot both the RGB and depth footage simultaneously. Since I was not using Depthkit’s built-in visualizer, an additional program was later developed to post-sync the two footage based on the milliseconds tags of the depth sequence.
For generating the cityscapes, I programmed another separate generator to produce images of random aerial views of buildings, using brightness to indicate each block’s altitude. The images were later imported and read by the system the way similar as Kerli’s depth sequence. The mapping of the pattern is also affected by each host cubic cell’s “gravitation mode”, which changes the pattern’s facing direction.
The entire music video is programmed and generated using Processing, with a few slight radiant blur effects done in Premiere during composition.

The project uses the magic and visual contradiction to transit from the digital language to the analog world. Construction of letters on a mirror creates new realities with the reflection, which are neither truth nor falsehood. With an obvious ludic intention, this project carries out a typographic investigation to return to the paper what it gave to pixel. In other words, to simulate pixel with paper when we are used to do it the other way round.
A personal perspective on the change of era that there has been in the construction of fonts and an invitation to reflect on how to generate images with #typography
A young man can’t help but see his girlfriend as various objects - including a french tart. Perception, misunderstanding and indifference are explored in this darkly funny animation about the foibles of romance.
