Meanwhile in Uruguay... it's summer!
This nice animation was created by [url=https://tube.geogebra.org/fvitabar]Fabián Vitabar[/url], coordinator of the [url=https://www.facebook.com/geogebrauruguay]GeoGebra Institute of Uruguay[/url], as a part of his demonstrative talk at the [url=https://tube.geogebra.org/material/simple/id/1447779]GeoGebra Global Gathering[/url], July 2015, Linz, Austria.[br]It is surprisingly easy to create a movie like this by using GeoGebra. Fabián also describes that in a [url=https://tube.geogebra.org/material/simple/id/1408699#material/1156115]step-by-step tutorial[/url] how to build such a nice animation from scratch.[br]His students also created nice and funny animations, for example one about [url=https://tube.geogebra.org/material/simple/id/1045641]a man who is playing with his dog[/url].
