Nature and technology. Typical and unexpected. Wandering through the city squares we stare at our smartphones or look under our feet and do not notice the harmonious interaction of the environment. Technology changes us and the world. But it’s high time we paid attention to nature. The cut and worked tree becomes a wooden baby seat suspended in mid-air, showing the soul of the tree that became a material and utilitarian object. And now the trees react to your presence, remind you they are still alive, looking for communication and requiring your attention. The trees along the alley are decorated with LED waterproof tapes. When you walk past the tree, movement sensors react and the light-emitting diodes attached to the tree light up, creating various patterns. In some cases (when several sensors react) a short musical phrase turns on, it sounds from the mounted piezo speakers, then every tree sounds with its own melody. The project runs since 10 June 2016. Working hours: daily, from 8 p.m to 4 a.m.
