very simple idea:
you go to a wood with a lot of coloured ropes.
you start to tide them on the trees.
all the ropes go from a tree to another in order to create a sort of coloured "wall" that directs you.
you use the trees as the pivots for your paths through the forest. it's just a matter of uniting points to create a maze. a natural maze!
the beauty of the forest keep untouched. it's just a game. now you have a labyrinth inside a forest. it's not claustrophobic. it's not damaging the environment. it's just colour between the trees. moving slowly at the winds.
and now enter. could you reach the exit?
