The Helicone transforms smoothly from a helix to a pine cone and back with a simple twist of the handle. The motion is fluid and reversible, making it an engaging kinetic toy. Its design draws inspiration from natural plant structures, incorporating mathematical principles like the Fibonacci sequence and the golden ratio. Constructed with 38 precisely laser-cut wooden pieces mounted on a brass tube, the Helicone includes a solid wooden display stand and arrives in a magnetic-closure gift box. Designed by John Edmark (USA) and manufactured in Taiwan, it functions as both a hands-on fidget toy and a decorative desk piece. Due to its delicate wooden arms, the Helicone should be handled with care to avoid damage from drops or impacts. For optimal use, grip the handle firmly while spinning—avoid rubbing it between palms. Suitable for display, stress relief, or as a thoughtful gift.
