A zoetrope on a giant humming top.

Melting is a zoetrope on a giant humming top (diameter 75cm) with a repetitive animation of floating patterns of drops on its surface. By omitting information the animation is created, what does that say about the animations you see every day?

This installation is a giant humming top (diameter 75cm) with a repetitive animation of floating patterns of drops on its surface. With use of strobe-light, spiral patterns and the turning of the top, an innovative and experimental animation will be made by use of trompe l'oeil effects.
The animation is inspired on the zoetrope, rotating wheel-spoke patterns, Fibonacci arrays and phyllotactic spirals from nature. Patterns of drops are designed on the surface of the top. With the animation the top seems to melt and flow. The pattern of the animation is fixed and is a 3D-printed layer on the surface of the top. By rotating this layer and lighting it with strobes gives the animation of the zoetrope.

The inspiration for the animation on this giant humming-top comes from a few subjects:

A zoetrope is a historical kind of animation. It's a repeating, turning and historic toy, like a humming top. The pictures in the drum will give an animation while watching through the fissures in the drum.
With a wheel-spoke patterns a toy top seems to change in direction of rotation while slowing down in speed. With changing the amount of spokes along the radius of the toy top the direction of rotation even seems to alternate with the radius.
This can be seen in the a small demo using the following youtube-link:

Spiral-shapes from nature and Fibonacci array's
Fibonacci array's treats structures and relations of spiral shapes in nature, the so called phyllotactic spirals, see the picture of the coneflower. The coneflower is formed by spirals in two different directions. Each direction has a certain amount of spirals, these amounts of spirals always have a determined relation to each other, following the so called Fibonacci array's.
These spiral structures will be the basis of the animation on the surface of the giant humming top.

Floating drops
I will use the mathematical Fibonacci array's and the phyllotactic spirals as a basis for my patterns on the surface op my humming top. The patterns will be made of drops so that the surface seems to flow or seems to melt. Two different patterns will be integrated by playing with the amount of array's and spirals so that the patterns seem to flow along each other.

With continuous light we see the rotating humming top without a pattern. The animation only can be seen with the light pulses of the strobes. Between the light pulses our eyes do not receive information about the movement of the humming top, but it does rotate a certain angle. Our eyes wait till they see the next light pulse and our mind makes the animation of the flowing drops. Strobe lights erase the information between the light pulses and with this lack of information the audience will make the animation. This is how our mind works!

With all the information we see on all the social media we must take care about the parts we do not see, as with a certain selection of information we can make our own animations and images and these do not need to give the whole picture.
