This Interactive Guide Makes the Discrete Fourier Transform Visual and Fun
Seeing Circles, Sines, and Signals
This eccentric, pop-science introduction to digital signal processing uses interactive visualizations, animations, and sound to explain the Discrete Fourier Transform. It prioritizes visual learning over linguistic, favoring simplicity and engagement over rigor. The author recommends it as a supplement, not a sole resource, and points to more formal texts like Lyons' Understanding Digital Signal Processing and the Coursera course by Prandoni and Vetterli.
One reason math texts are so abstruse and technical is because of all the specifications and conditions that have to be put on theorems to keep them out of crevasses. In this sense, they’re like legal documents, and often about as much fun to read.

looks like we both created educational materials about the same topics - except yours clearly is higher effort in terms of prose and human effort.
Was toying with the idea that with everyone vibe coding niche educational sites (this is a claim about myself, not this site) it would be nice if that effort could go into building an auditable library of widgets/ educational resources users could trust.
Disclaimer: my concept is a stalled WIP/ completely vibe coded, but for me it was fun POC of a widget registry that can be served into chats via mcp

Reminded me of this crazy good video/game (a game with no assets because graphics, sounds and music are just built out of sin functions) https://youtu.be/Qr3VsZYQy4s?is=IBX2bA1jitw38q0u

In the Figure 1, I expect the smallest circle to draw the figure.
