I've been experimenting with the PIO (Programmable I/O) system on the new microcontroller from Raspberry Pi. These are coprocessors for which the user can write code in a bespoke assembly language (PIOassm) to drive the GPIO ports. You can do really interesting stuff with these, like implement high-speed communication protocols (e.g. VGA) or offload tasks like driving stepper motors.
I've also been really interested in fractals and chaotic systems. For me, they're a nice bridge between interests in engineering and art. That's why this is drawing the Lorenz system in particular.
