Three Shiny Apps to Celebrate the Beauty of Maths

Mathematics knows no races or geographic boundaries; for mathematics, the cultural world is one country (David Hilbert)

One of the best decisions I took this year related with this blog was to move it to my own self-hosted domain using It allows to me, for example, to embed dynamic JavaScript visualizations like this one. Another thing I can do now is to upload my Shiny Apps to share them with my readers. In this post I have gathered three Apps I made some time ago; you can play with them as well as get the code I wrote for each one:

  • The Harmonograph: This App simulates harmonograph drawings. An harmonograph is a mechanism which draws trajectories by means of two pendulums: one moves a pencil and the other one moves a platform with a piece of paper on it. Click here to try it.
  • Shiny Wool Skeins: This App, inspired by this post, creates a plot consisting of chords inside a circle . You can change colors as well as the number and quality of the chords. Click here to try it.
  • The Coaster Maker: With this App you can create your own coasters using hypocicloids. Click here to try it.

I want to thank to my friend Jorge, without whom I would not have been able to make Shiny work in my server.
