I have been at the Bridges 2018 conference in Stockholm to present my work on kaleidoscopes. My paper “Kaleidoscopes for Non-Euclidean Space” has more details than this blog and is more coherent. The Bridges Organization, which promotes connections between mathematics and the arts, held this conference. You will find a lot of interesting ideas and images on its site.
I have created a new site “geometricolor.ch” to host interactive pages. There, you can create your own kaleidoscopic images with the browser app “Kaleidoscope“. You can play with the interactive presentation “Bridges 2018” to learn more about its methods and to get some intuitive ideas about elliptic, Euclidian and hyperbolic geometry.
