Some basic lissajous :^)

There are many variations of this one depending on which parameters you use, but this is an example of a Lissajous curve

Lissajous in a Box

My first ever attempt to use traditional descriptive geometry techniques to create an image of the 3D Lissajous figure described by x=sin(t),y=sin(2t),z=sin(3t).

The "3D" axonometric image in the center is maybe slightly reminiscent of a human heart. It is created from the two 2D Lissajous figures, described by sin(t)/sin(2t) (the butterfly on the bottom) and sin(2t)/sin(3t) (top right, in blue - mouth of a monster worm ;-) ? ).

Actually, there are two curves of each type, one being the twice the size of the other. I am coloring the surface spanned between them, as if it were a ribbon. Also showing the cubes that contain each of the 3D figures. The 2D Lissajous figures are in turn created from the respective sine functions (also shown as black curves) ... which in turn are created from the y co-ordinate of points on a circle.

bitches be like “look at my new blorbo” and it’s just a mathematical concept

Lissajous Curves: Roller Coasters

Roller Coaster design This post continues from the previous post on Lissajous Curves.  Make sure to read that one first! We can design a rollercoaster track by using the following Lissajous Curve: This gives the following graph: Ground level is given by the line y = −50. Distances are in metres and t is measured in seconds. Customers ride an elevator to the starting point (0,50) where the ride…

Homemade vector driver circuitry for a cathode ray tube.

I want you to read that again.

Jarrett made this himself from scratch, and controlled it from a raspberry pi attached to the serial terminal below it that he found in a ditch! The pi was watching live aircraft data from ADSB, so we could see real air traffic in the radar mode. He also had some interesting lissajous patterns, and a rendering of a witch.

It was one of my favorite exhibits from VCF Southwest 2023

Improvisation using no-input mixer, stylophone, loopers, and my drum synth (pure data on raspberry pi) + midi controller. I have updated my drum synth patch to add a (non-quantised) tap-a-pattern function for the kick drum hence the wonk.

The visualisation is a Lissajous figure, produced by software called PrettyScope.

Above, in the Divine plane… there is a golden circle and in the center there is a Point,

where the Divine, the origin of everything, is located. From the Point different vibratory

radiations move outwards toward the Cosmos and, surrounding it, in blue tones are,

among other symbols, the Signs of the Zodiac (The Wheel of Life).

When a plant, animal, or human dies, the Vital Life Force leaves it … and then the atoms break down into electrons, protons, and neutrons. In the final phase of disintegration, every atomic sub-particle rejoins the Cosmic Keyboard according to its vibratory nature. Thus, no element participating in the constitution of a living being is actually destroyed in the course of physical decomposition. Its atomic sub-particles merely undergo a transformation and purification that allows them to return to their initial state. Only

appearances lead us to liken death to some kind of destruction, for actuality is entirely different.

El Teclado Cósmico (The Cosmic. Keyboard) (1961) Nicomedes Gómez the Golden circle refers to the 'golden' phi ratio shaped torus , which in plan view looks like a circle - the centre point is the center of the torus , where the golden ratio spiral compresses to its point of origin, from there the in-phi-nite expansion of this spiral creates reality - theres an app called iThrve - this app when used by everyone that tries it, reveals that when they meditate (stop thinking) the app shows our heart generates a cascade of golden ratio harmonics on the flat screen of our mobile, the waveforms of peaks and dips is really in 3D a golden ratio spiral.

Whoa, I think I may have just rediscovered one of my earliest formative influences. The intriguing geometry of the cycloids and lissajous patterns. The jarring contrast with the bizarrely shapeless and unformed face, intensified by how completely unsynchronized it is with the ominous, faintly-menacing audio.

If Very Small Me had been familiar with the concept of eldritch Lovecraftian horror, this is what I would have thought it was like. It's only slightly less nightmarish now that I'm old.
