Spanish designers Luzinterruptus have created an installation in Madrid by attaching LED lights to leaves.
Called An Almost Ephimeral Autumn, the installation involved making the leaves appear to float by supporting them on wires and lighting from below.
"Finding somewhere in Madrid with Autumn at its best was hard but in the end we did," say the designers.
"For our installation, we lit 200 dry leaves and lifted them from the ground until it seemed as if a truly soft breeze of light had made the Autumn fallen leaves raise into the air."
