SparksMaths | The Chaos Game - Geogebra Build - as seen on Numberphile @SparksMaths | Uploaded 2 years ago | Updated 2 hours ago
In this video I build a simple @GeoGebraChannel simulator to generate the fractals seen in the Chaos Game (wikipedia: en.wikipedia.org/wiki/Chaos_game), and as seen in the @numberphile video: youtu.be/kbKtFN71Lfs

First part is short and fairly straightforward.
Second part is tinkering with the generalisations in GeoGebra.
Third part I get a bit carried away playing with fractal dimension and how the GeoGebra variables affect this. You have been warned.
