Chaotic Double Ring Pendulum: a new design on the chaotic double pendulum. Interesting and intricate motion arises from a simple assembly of two physical pendulums (one attached to the end of the other) with the kinetic energy of the system moving back and forth between the two rings until friction damps away the energy. Chaotic motion is characterized by extreme sensitivity to initial starting conditions, tiny differences in how the system is released leads to dramatically different outcomes each time. This exceptional design by Jason of Milieu Tech Design seems engineered to maximize the exchange of energy between the rings.

3D Phonotrope Spinner: slinky on an escalator! When the rate of rotation matches the rate of the smartphone video process (wait for it) 12 animated 3D-printed slinkys “spring” into motion. The 3D printed and precisely placed depictions of the famous toy is specifically designed to interact with the video process, similar to the animation effect of a flip book, but in a repeating cycle like that of the phenakistiscope, the 1833 invention that started moving media animation that lead to the development of movies and video.

Roman Dodecahedron: these mysterious forms were made between 200 to 400 AD and more than 120 of these hollow bronze objects have been found in the northern regions of the Roman Empire. Not a single one is marked with letters or numbers, but all have holes of varying sizes and all feature knob like protrusions at each of the vertices as shown in this 3D printed replica. What was the purpose of these dodecahedrons? No one knows! Despite more than 50 published proposals there is no academic consensus.

Warped Spiral Kinetic Art: a slight breeze will set this stainless steel sculpture into graceful and mesmerizing action. When spinning the rotation creates translational motion along the vertical- and each helix in this version has a slight asymmetry that adds to the complexity of the perceived motion.

Transforming Tetrahedron: clever gear linkages allows this tetrahedron to transform to its Platonic solid dual- another tetrahedron it turns out. Halfway through the transformation the object becomes a symmetric 12 pointed star with the tip of each point indicating a vertices of a cuboctahedron. Another fun 3D print creation of maker designer RuvenBals

Floating Rings Illusion: three rings seemingly roll/spin like a coin on top of each other, edge to edge, when in reality they are connected rigidly into an assembly and rotated. This fun 3D print used glow-in-the-dark filament which adds new aspects to the illusion- what do you see? A 3D print designed for any turn table/record player by Ryan Leathers.

GIF Film Card II: Next generation lenticular motion that can stack many images to produce two seconds of video motion on a physical semitransparent card. Classic lenticular motion is produced by tiny cylindrical lens arrayed in such a way that allows for one of multiple images (usually fewer than 5) to show depending on the angle of view. This multiple image high resolution lenticular features three scenes from a famous series about a fictional and infamous Heisenberg.

Magnetic Repulsion Fidget: a strong dipole magnet is suspended between two more dipole magnets, one fixed to each end. When the center magnet is displaced it rapidly oscillates in an oddly satisfying way until the slight friction present dissipates the energy. This fidget toy provides a very tactile experience of invisible magnetic fields and forces.

Mirror Anamorphic Cup & Saucer: the cylindrical mirror of the silver cup reflects and reveals the distorted scene of a carousel ride with four horses and the buildings of Macau Heritage City. The shape of the mirror allows for a mathematical operation, a type of affine transformation, to map the distorted image on the plate to the restored image reflected on the cup. A nice example of mirror anamorphosis through the medium of ceramics.

Circa 1981, Physicists transmute Bismuth to Gold: Particle accelerators make possible the ancient alchemist’s dream—but at a steep cost
The Alchemist: cast from diamagnetic Bismuth, a neodymium cube magnet levitates trapped between the hands of the ancient scholar. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the cube shaped magnet supplies the field. Diamagnetic fields are pretty weak though so a cylindrical neodymium magnet hangs above the figure and is adjusted to help lift the cube magnet against gravity. Trapped in equilibrium by these magnetic fields, the slightest air currents can send the cube magnet dancing. Although alchemists never succeeded in transmuting lead to gold, in 1981 physicists used the particle accelerator at Berkeley to shoot Carbon nuclei at thin foils of Bismuth- the resulting collisions did produced a tiny amount of Gold atoms! So modern nuclear physics, applied to the element Bismuth, finally accomplished the aspirations of the alchemists. ?Another amazing creation by Ernie McElhannon.
