Mirror Anamorphic Lenticular Cup & Saucer: a flamingo sits in a nest of flowers, revealed when the cylindrical mirrored cup is put in place. This beautiful design by Luycho uses both mirror anamorphic reflection and an accordion type lenticular dual image where turning the plate 180 degrees trades images- using my new photography turntable to nice effect. Art meets math and physics!

Tensegrity Table: A wonderful three string version of the suspension equilibrium table. The LUNA tensegrity stand is 3D printed and then painted by hand, with designer Anthony Yap incorporating a celestial moon phase motif to nice effect, and clear nylon fishing line for an almost invisible means of support. Another configuration related to the concept of tensegrity invented by Kenneth Snelson and made famous by the architect Buckminster Fuller in 1949. 

Shadow Stereographic Projection

These mathematical art objects are created by Henry Segerman and available here: 
From Shapeways: BUY NOW Mathematical Art 

Wikipedia has a nice introduction to the math and applications of stereographic projection

Shadow Stereographic Projection: 3D printed sculptures that cast geometric shadows. When illuminated by a point source of light (placed at the top pole of the sphere) the shadow cast by the rays of light represent a one to one mapping of the points on the sphere to points on the plane- creating a square grid, and a honeycomb of regular hexagons. Stereographic projection is often used in representing the geography of the globe of our planet on to a flat map. Mathematical art by Henry Segerman. 

Novatrope

From novatropes.com: BUY NOW: Novatropes

Novatrope: this electro-kinetic sculpture uses strobing LEDs to animate a fractal inspired spiral geometry- similar to a 3D zoetrope. The shape and motion perceived by the eye depends on the ratio of the spin rate and frequency of the strobing light (adjusted with the silver knob). Each Novatrope comes with multiple 3D printed translucent sculptures each based on phyllotactic spirals such as the well known Fibonacci curve. A wonderful new type of kinetic art infused with math, physics, and psychophysics by Brandon Keeber and his design team.

Click here for similar itmes: Zoetropes

eyeMo Linear Zoetrope: the physics and psychophysics of motion animation- still images flashed in rapid succession produce the illusion of motion through persistence of vision. This unique version uses an array of lenses, and the images are flashed one by one as the series of lenses moves past the eye. When the image flash rate is above the flicker fusion frequency (approximately 16Hz) we perceive fluid motion- the basis for all movies and TV.

Computational Caustic Projection

Exclusive offer: get this limited edition sample of this new artform here:

From STEMcell Science: BUY NOW:  Caustic Projection Lion

Computational Caustic Projection: an image is formed by refraction through a free form lens in a new process that utilizes the physics behind how light is concentrated into caustics. This piece of molded acrylic has a surface of slight but precisely constructed curves, that when lighted by a broadband light source (Maglite flashlight bulb), projects an image of a lion onto a plane. This is not a hologram, but instead a new proprietary light redirection technology by the company RAYFORM. Special thanks to @rayform technologies for sending me this sample.

From Amazon: BUY NOW MaBoRun Marble Run 

MaBoRun Mini IV: rolling marbles doing tricks as potential energy of gravity is converted to kinetic energy. In this mini-marble run a battery powered auger conveyor (Archimedes' Screw) brings the marbles back to the top and conservation of angular momentum produces a simulation of decaying orbits as the marbles whirl down the the main funnel shaped feature.

From Etsy: BUY NOW Tessellating Geckos 

Tessellating Geckos: MC Escher inspired lizard cutouts interlock precisely to tile a surface with no overlaps or gaps. Laser cut from maple, walnut, and cherry wood by maker/artist Craig Caesar and inspired by MC Escher’s “Study of Regular Division of a Plane with Reptiles” 1939. G4G week: Martin Gardner wrote about the art and math of Escher in 1961- which helped create the popularity that his work has experienced ever since.

Wilberforce Pendulum

Classroom demonstration models are available here 
From Amazon: BUY NOW Wilberforce Pendulum Apparatus 

Wikipedia has a good introduction to the physics: Wilberfocre Pendulum 

Wilberforce Pendulum: the mass and spring properties of this device are tuned such that the kinetic energy transfers back and forth between bouncing and twisting in this special coupled harmonic oscillator system invented by physicist Lionel Wilberforce in 1896. If any system is free to oscillate in two or more ways, the energy can transfer between the different modes- note that the bouncing completely stops for a bit, and then the twisting briefly stops- and back and forth with a period of energy transfer at about 15 seconds between the bounce mode and the twist mode. Here the mass and rotational inertia (altered by moving the four small masses in and out) are adjusted so that the resonance frequency of twisting is equal to the resonance frequency of bouncing. This system will complete up to 5 cycles (from rotation only to bounce only and back) before the energy is dissipated.

Fine Wood Tippe-Top

Handmade flip over tops available here: 
From Art of Play: BUY NOW Flip Over Tops

From Educational Innovations: BUY NOW Tippe-Tops 

Fine Wood Tippe-Top: spinning things often have surprising physics! This lathe worked version of the famous flip-over top is made of ebony and wood from the pink ivory tree. Friction with the mirror provides a torque that acts on the existing angular momentum of the top to flip it over. The top will stay flipped until the spin rate slows down enough to where its center of mass pulls it back to the resting position.

The amazing green magnetic viewing film is also available: 
From Educational Innovations: BUY NOW Magnetic Field Viewing Film 

Here is the 1974 patent showing the very simple circuit of this device. The spinning dipole (the top itself) induces a current in one of the coils, and this current is fed to the base of the transistor turning the electromagnet on when the top is near. 
 

"Top Secret": this top will stay spinning for more than a week- because it is actually a motor! The top is a dipole magnet (as revealed by Magneview film) and the base has an electromagnet that gives the dipole a push when the top comes near the center. An ingeniously simple circuit consisting of only a battery, a coil, and a transistor, is activated when the spinning magnet nears the coil turning on the electromagnet to give a boost to the spin of the magnetic top.


Micro Racer in a Glass

These micro racer cars are sold under many brand names, and most come with a clear sphere to demonstrate this centripetal acceleration phenomenon. 

From Amazon: BUY NOW: Micro Racer + Sphere

Micro Racer in a Glass: This tiny battery powered car overcomes gravity through centripetal acceleration and slight friction with the glass surface. With sufficient velocity the surface normal force supplies the centripetal acceleration. The car’s battery last for many minutes and is USB rechargeable.

From KiwiCo: LEARN MORE: Tinker Crate Subscription

Glow Trace Chaotic Pendulum: this fun and DIY kit features a UV diode to trace the intricate path of this double pendulum system on to a phosphorescent screen, revealing the physics of chaotic motion. It’s amazing that such complex motion can arise from a simple assembly of two pendulums, one attached to the end of the other. Chaotic motion, such as that observed here, is characterized by extreme sensitivity to initial starting conditions, tiny differences in how the system is released leads to dramatically different outcomes each time. 

 

Feel Flux Loop

From Educational Innovations: BUY NOW Magnetic Viewing Film 
From Amazon: BUY NOW Magnetic Viewing Film 

Feel Flux Loop: original (copper) and the "Skill Flux" version (aluminum)- toys that use Lenz's Law to manipulate a very strong neodymium magnet. A changing magnetic field (such as that from a falling magnet) induces an electric current in the copper, which in turn produce an electromagnetic field (but of lesser strength) with opposing polarity. Interestingly the magnet falls a bit faster through the aluminum even though the walls are thicker- Al is only about 60% as conductive as Cu- so it takes more material to induce the needed magnetic field using aluminum. Interestingly the Al tube is about half the mass of the Cu one, even though it is larger in volume. Swipe to see the effect via magneview film which allows a visualization of the magnetic field- note that the field extends and is visible right through the thick copper.
