What is this 'Dot fever' about?

[size=150][b]Hi! Welcome to the Dot fever series![/b][br][br]In Twitter I saw some amazing animations with red and white dots by [url=https://twitter.com/ntsutae]ntsutae[/url]. You can see the tweet [url=https://twitter.com/ntsutae/status/1327422887515439104]here[/url]. These animations were made with the minimalistic creative coding environment called [url=https://tixy.land/]tixy.land[/url] created by [url=http://aem1k.com/]Martin Kleppe[/url]. After studying the source code I thought it was possible to make a GeoGebra (GGB) version of these animations. This book contains the results of my implementation in GGB.[br][br]I would like to thank [url=https://www.geogebra.org/u/thijs]Thijs[/url] who helped me to improve the GGB script. If you like to see more amazing applets, you must check [url=https://www.geogebra.org/u/thijs]Thijs[/url]'s work.[br][br]Finally, if you like to see the script, please download the GGB file and look for the button with label: [i]Script. [/i]Or check the last chapter of this book to see the initial and improved versions of the script.[br][br][b]Enjoy![/b][/size]
