This mobile is called “Calliope”. It’s larger than it appears because these shapes are very chunky. The mobile measures roughly 30” high by 24” dia. (75 x 60 cm) and is made of aluminum and steel.
To enhance its festive nature, I’ve painted the wires as well. This and its large size/light weight makes it more suitable for indoor use.
