Processing 3, programming, Python, #3D, #fractal, #three dimensions, #three-D, #three-dimensional
In July of 2015 I published my Menger Sponge post. As I said there, the true Menger Sponge is a three-dimensional object, but due to the lack of 3D-integration in Pygame, I only showed one of the six cube’s faces. The two-dimensional fractal is officially called Sierpiński carpet while the three-dimensional object is really called a Menger sponge.
To achieve the three-dimensional cube, I used Processing 3 together with its Python Mode.
The actual fractal is colored with a pseudo-randomly chosen color. All its smaller cubes then get a slight color shift. The cube rotates slowly, with a different speed on each of the three axes.
- ‘Space’will advance the cube’s fractalness,
- ‘q’ will save an image of the current fractal’s state.

MicroPython, programming, Python 3, #micro, #microcontroller, #pyboard
Being a big fan of Python, I recently got a MicroPython Board.
MicroPython is a simple to use micro controller which runs Python 3. To put code onto it, you simple mount it as you would do with a USB flash drive, copy your
main.py to it and restart your MicroPython.
As a simple “Hello world.”-program, I wrote this counting script. Every time you press the built-in button, it counts up by one. Using the four built-in LEDs and binary number representation, this counter can count from 𝟢 to 𝟣𝟧 and then wraps back.

Recreating the famous falling bit effect from Matrix using python and curses.The individual bit strips are separate entities, falling to the bottom and then being moved up again with a different 𝑥 value. They also get a random speed between one and five deciseconds.
