He speaks a mysterious language. And who knows from whence he came.

Your little martian will feel right at home with a glow-in-the-dark solar system mobile from Eureka-based kinetic artist Julie Frith.

Beautiful by day or night, the mobiles are light as a feather and orbit with the slightest breeze. Created by hand from nontoxic plastics and stainless steel wire, they feature Baby’s new home (Earth) and the seven other sun revolvers.

Frith also makes a line of Foamobiles with baby-safe EVA foam petals that can be custom colored to match your nursery.

They’re out of this world.
