A Python/pygame mode for EYESY inspired by the Numberphile Youtube video “Beautiful Trigonometry”.
# EYESY
Knob 1 – offset the circles, oscillating between positions A and B.
Knob 2 – amount of circles.
Knob 3 – speed of circle oscillation.
Knob 4 – color change.
Knob 5 – background color change.
Audio/Trigger – toggle direction of circle oscillation.
# MIDI NOTES
Lower notes decrease values, higher notes increase values. Values change as long notes are being held and the values are within predefined limits.
[60, 61] – Coarse-tune size of circles.
[62, 63] – Fine-tune size of circles.
[64, 65] – Coarse-tune size of spokes.
[66, 67] – Fine-tune size of spokes.
[68, 69] – Amplitude of wheel hub x-axis.
[70, 71] – Oscillating speed of wheel hub x-axis position.
[72, 73] – Wheel hub rotation speed (only visible when the wheel hub is oscillating on its x-axis position).
[74] – Toggle direction of wheel hub rotation.
[75, 76] – Amplitude/range for oscillating colors.
[77, 78] – Speed of oscillating colors.
