These have got to be some of the more beautiful forms I’ve ever seen. Check out the video here to see the creation of these wondrous colors and shapes.
Millefiori by Fabian Oefner:
The shapes, you see in these image are about the size of a thumbnail. They are created by mixing ferrofluid with water color and putting it into a magnetic field.
Ferrofluid is a magnetic solution with a viscosity similar to motor oil. When put under a magnetic field, the iron particles in the solution start to rearrange, forming the black channels and separating the water colors from the ferrofluid. The result are these peculiar looking structures.
