A sleepytime scene of animals bandying about a tree at night makes this one of our bestsellers for a child's room. Elements of this Djeco mobile glow in the dark. Measures 32x20 inches when assembled. Mobiles, kinetic sculpture, have delighted people of all ages for a century. Pioneered by artist and sculptor Alexander Calder, they add a fascinating life and movement to a room. Once described as visual poetry, these symphonies of subtle movement are elegantly balanced and float in perpetual soft motion. They transform spaces otherwise not seen, providing visual stimulation and interest with whimsy, humor and a design aesthetic not often found in children’s room décor. Perfectly balanced, all can be hung right out of the box, with little to no assembly required. Enjoy the slow dance and soothing inner peace with this new focal point to any room.
