Yesterday (29th of April 2017) I was at a Brony Meetup in Straelen where the organizers had contacted a local primary school to get the permission to draw chalk ponies on the school playground. The result were some really, really awesome chalk images on the schoolground (I will add links to the work of the other brony artists here as soon as it is uploaded). I kind of regret that I cannot be present when school there starts again. I bet the kids there will enjoy the temporary new design of their schoolground.  
This is a drawing of Leafhelm, the character I am playing in a My Little Pony pen and Paper RPG.
