I've been writing webgl shaders at work this week and noodling with the details to make things look like physical camera effects but occasionally I'll get something wrong and see results that look similar to the stuff in this article and I have to say it is just so much more fun than the standard image effects.

Sure there might be limited use cases for it visually but playing with the models we've built up around how graphics in computers work are a great way to learn about the each one of these systems. Not just graphics but fundamental math in programming, how GPUs work and their connection to memory and CPUs, how our eyes work, how to handle animation/time, and so on.
