ZOG Industries Inc proudly presents the first ever Linux hardware driver in Bash.

So, guys, if you run this shit with root permissions, it may burn your computer to the ground, but if you're lucky, it will read current time and date from the hardware clock.

Understanding Fourier series and analysis

http://complexity.zone/fourier/

Sixty Wheels is a Windows application for illustrating the concepts of Fourier Series and Harmonic Analysis. The application provides 60 turning wheels which can be connected to each other at any point on their perimeter. The radius, phase and turning speed can be set for each wheel. The program shows the front view of the turning wheels, which resembles a Harmonic Phasor. The side is also shown so that its 'real' (or 'imaginary') component is shown. The path followed by the side view is plotted against time on a graph.
Optionally, you can draw a periodic waveform directly on the graph (when the "I draw graph" option is checked). You can then press the "Fourier" button and the application will calculate the sizes, phases and speeds of the wheels to reproduce the waveform. Some presets with interesting signals are also included.

I made this program back in 2002 to illustrate Fourier series and analysis. It's an old project, but I still think it is fun and educational.
I am considering making a more modern version. Are there any other programs/apps similar to this?
Any questions or feedback is welcome.
