Frictionless ferrofluid becomes magnetized in the presence of a magnetic field. Developed as a liquid rocket fuel for NASA in 1963, ferrofluid is an oily black fluid full of suspended nano magnetic particles. The liquid itself assumes the shape of magnetic lines of force. It forms spiky peaks and valleys that reveal the invisible structure of magnetism. This program was filmed in slow-motion macro video. Music by KRON.

A free-form exploration of computer-aided designs (CAD) for nanoscale construction. These digital blueprints are used to manufacture miniscule nanostructures as intricate as the Eiffel Tower. Their repeating fractal-like octagonal design imparts great strength and flexibility, resulting in one of...
Vintage scanning electron microscopy of a 1980s computer chip. The images were created through the excitation of electrons rather than by the reflection of light. Hues of color were created with rare in-microscope 'lighting' using 3 electron beams. Magnified hundreds of times, the semiconductor s...
A colorful macro kaleidoscope of laser light reflecting on ferrofluid. Ferrofluid is an oily fluid that becomes magnetized in the presence of a magnetic field. The black liquid takes the shape of magnetic lines of force. Music by KRON.
