It's a french garden like an improvised theater of experimentation.
When you walk into this garden, you can imagine the hedge strangely moving behind you as you go by...We made an invisible contact carpet under the ground. When you walk on it, you start quiet electrical motors who moved the hedge slowly.
In the center of the garden is a pond. Floating on the water, a few balloons are there like they have been forgotten. If you pay attention, you can hear they are speaking together in an incomprehensible language. If you take one of them in your hand it's going to be very angry. It will shout at you and change color to red. For this, wireless speakers where put inside the balloon. The balloons become waterproof sound modules.
