As my friends may tell you, i love to take photos of ferrofluid thats repsonds to a maganetic force. i find these images very hypnotic and mysterious to the eye. the reason i do these is to enable a represenation of space that is created by a current and movement.
the images vary in styles due to how close the magnet is to the ferrofluid. the closer the magnet, the tighter the "spikes" are. the further away, the images are loose and fluid.
