When a ball falls out of one geyser, the sloped mesh surface encourages it to roll counter-clockwise to the next geyser. When a ball enters a geyser, it interrupts the flow of water, thus releasing the geyser’s current ball, which then moves on to the next geyser. Aquabatic Balls Aerobatic Balls — Ping-Pong balls are suspended by 12 air streams. The balls interact with each other in a chaotic fashion, each of them affecting the air stream around its neighbors. The behavior of the system can be adjusted by varying the number of balls and the air velocity. Polyhedral Kaleidoscope — Unlike a regular kaleidoscope in which the three mirrors form a triangular prism, the mirrors in the polyhedral kaleidoscope form a truncated triangular pyramid. This results in the replicated images no longer being coplanar (as in a regular kaleidoscope), but instead meeting each other at an angle. Polyhedral Kaleidoscope Polyhedral Kaleidoscope (Rear View) — Changing patterns are the result of floating balloons blocking red, green, and blue lights. Chaise Lawn Chaise Lawn Programmable Rhythm Fence — A concept for a circular fence in which each stave would have two orientations: flush, and angled. By selecting different combinations of flush and angled staves, different rhythms would be produced by running around the fence with a stick. By angling just the staves that share a given symbol one can create a pre-programmed rhythm. Coupled Polarizing Filters for Stereo Camera Micro Kettle — Makes boiling water in the microwave safe and convenient by turning one's mug into a teakettle that whistles when the water boils. // JTE changed from width: 620px; height: 520px; border: 1px
