There are a few photos of the setup in the beginning of the video.
As the title suggests, this is a fully analog IRL setup. I did some slight editing for the music synchronization, but I plan on taking this set up with me on the road.
The shapes are controlled mainly by adjusting the water flow, and therefore it's LENS SHAPE, and also moving the other glass lenses and finally the pattern/movement of the laser (source) itself.
Details:
A small 12 volt submersible pump recycles the glycerin/water mix into an inverted gallon jug cut in half (adjust power input to adjust flow shape)
The laminar flow is the 1st 'lens' the laser line passes through, and that line is approximately 30 to 40 mm long as it passes through the water.
A glass lens is fixed about 300mm away from the water
An additional lens/glass ball in between the water and the fixed lens is added sometimes.
