Share your creation through social networks

[stephanemagnenat]

It would be great to have a way to share one's creation by twitter (or facebook, google+, etc.). By implementing an URL that redirects to an app as suggested by @davidjsherman here and on aseba-community/aseba#700, one could directly get the code if VPL2 is installed, or install it otherwise.

An additional great and unique feature would be to do server-side rendering of an animation thanks to Enki to show the code in action, but that would be for a later step.
