Fourier Transform Visualizer

Fourier transform calculator and visualize which emulates an analog clock, giving fairly accurate, but mildly inaccurate readings, depending on the speed of your phone shortly prior to the calculation. It runs like an old machine, so great for that nostalgic vintage feeling. It's educational and can help one understand how the fourier transform works and it's also helpful for teaching how a stroboscopic tuner works, as the fourier transform functions similarly.
