Persistence of Vision
This kinetic sculpture is an attempt onto understanding ‘uncertainty’. It lets one experience the feeling of being motionless while still being in motion, and thus creating a visual polyphony.
The project was done as a part of the course – Kinetic Sculptures (7 weeks) in the year 2017 at National Institute of Design.
How does this happen ?
In a strobe lit room, the 3d sculpture spins rapidly with an optical illusion brought to life in two dimensions. Due to the phenomenon of persistence of vision, the forms appear to be frozen after a certain point as the imagery on the unit forms a flat optical illusion.
3D paper model of the optical illusion and a suitable mechanism was worked out. A gear box for high speed resembling that of a Manual Mini toy fan, was constructed. The assumption of the max speed that could be attained by hand cranking was 20 RPM. However, even after several attempts onto making different combinations (Ratio- 1:5 | MAX SPEED: 500 RPM & Ratio- 1:3 | MAX SPEED: 1620 RPM) of gear boxes, it never produced a uniform high speed for the effect to happen and thereafter, a DC motor was put into place.
