GIF file animated with open-source software.

I tested the Blender 3D version 2.76 with Inkscape and Synfig to make this GIF animated.
This is the result :

I used the default cube from Blender 3D to make a SVG image. 

Also I working with Synfig software to create this GIF. 

I will make one good tutorial about this GIF. 

I hope this will help you to find new ways to deal with the open-source software.
