Flow visualisation is a fast-evolving field that often sees the merging of technology and scientific endeavour. For this experimental video, a sans-serif logo was designed and 3D-printed, before being placed in rheoscopic fluid — a substance traditionally used to investigate liquid flow in physics and engineering research.
Rheoscopic fluid was designed to exploit the optical properties of guanine flakes — as they move amongst vortices created by the flow of the liquid they are suspended in, they reflect light in a way that reveals patterns of flow.
High-speed videography (a Phantom camera at 1000fps) was used to document the dynamic nature of the fluidic movement around the typography, which illuminated unusual vortices and turbulent flow specific to the fictional chemical symbol for Gobbledigook.
Rheoscopic fluid is no longer made, disregarded in favour of digital modelling techniques, and this short is a paean to this soon-to-be-lost interaction of light and liquid.
