All of these obstacles - just an illusion. To demonstrate this, and Nike has invited the masters of the genre 3D paintings on pavement - German artists Marion Ruthardt and Gregor Vosika in a Moscow park.
The five parks, one of those that have a running club Nike "I run", the artist depicted the bottomless pit, through which we can pass on a log, a waterfall, over which hung a rope bridge that rift in the earth, which can be overcome, jumping on the islands , drifting ice floe, and blocking the way, the closed gate.
