And he began to decorate the streets of towns and villages with their installations, all of which consisted of the same plastic cups. And he called his favorite hobby "Cuprocking".
Technique "kaprokinga" is very simple - you need to find a good fence is not very large-mesh netting, dial a few bags of cups and start to push them into the corresponding holes in the fence. Well, then paint the resulting structure at its own discretion - the result is obvious.
