Decay

phosporescent doped wall, laser system, control, programming and safety systems.

As if by magic, patterns are created then slowly fade before your eyes. A simple dark blue laser dot or line moves across the canvas creating a pattern revealed only as a fleeting after image- slowly fading as soon as it is created. It is the persistence of photonic decay that allows us to see that laser projections are merely dots of light moving so fast our eyes can not see them as individual dots, but rather blur them into complete shapes. Slowing down the laser allows us to see what and how we see.

Coherence, utilizes the special inherent quality of spatial coherence to create the illusion of infinite spaces and provides the magic that will illuminate one filament and not the one next to it. Exploiting this special and unique nature of lasers elevates this environment to more than just a science experiment by creating the appearance of internal illumination where there is none, motion where there is none and with the addition of a mirrored floor, produces a subtle perceptive disorientation while defining and marking space in infinite and mesmerizing ways.

This exhibit utilizes 2 synchronized RGB lasers to project onto hundreds of suspended filaments creating an oceanic undulating immersive environment of light.
