Feather Kaleidoscope: unique chamber filled with cut feathers provides the viewing material for this side-lit precision kaleidoscope by Carol Verde-Paretti. With every squeeze of the perfume atomizer bulb, a puff of air throws the feathers into a new arrangement leading to a seemingly infinite variety of stunning images on the five point mandala. Invented by the famous Scottish physicist Sir David Brewster (1781-1868), the kaleidoscope is an ultimate physics toy and entire field of artistic endeavor.

3D Print Planetary Gearset: amazingly this gear set is printed assembled, with interlocking herringbone teeth. The gears will not come apart, in fact this design can only be accomplished by 3D printing the gears interlocked with each other. Designed and first printed by Emmett Lalish in 2013, and this version with refined precision and honeycomb by Don Stewart.

Kinetic Magnet Illusion Disk: explore amazing phenomena from the physics and psychophysics of vision- give this disk a spin and the imparted angular momentum (along with precision bearings) allows for sustained rotation and a changing visual experience. The spiral design converts rotational motion to radial motion inward and outward, and the dots on the image seem to dance and blur as the flicker fusion frequency threshold of our vision is exceeded. Looks amazing in person, and on video additional effects can be made depending on selected frame rate. One of many designs available from artist Dmity Shytko.

Gyrobi Kinetic Toy 

Kaleidoscope Symmetry Physics: Two adjacent mirrors form the repeating image of a kaleidoscope, but the shape of the image is determined by the angle between the mirrors. This principle is demonstrated with three different symmetrical patterns using this beautiful set of precision teleidoscopes- angles of 36° (blue tube), 30° (green tube), and 22.5° (red tube), creating mandala stars with 5, 6, and 8 points. The angle for any symmetric star pattern of n points is just 180°/n. A teleidoscope is a kaleidoscope but with a lens on the end, such that the kaleidoscopic image is formed by whatever is put in front of it. Here the complex motion of a Gyrobi toy is used as the observation object.
