Please note that wood colors may vary. Infinity is a fascinating box whose purpose is to display or demonstrate the relationship between gears in such a way that can be observed clearly through the transparent acrylic on the top and bottom of the box. There is a 1 Euro coin embedded in the top cog that will eventually be released with the consistent spinning of the gears (hence its wonderful name!). A fantastic showpiece of mechanics in a "technology-trick" box. Made in laser-cut wood, acrylic, and stainless steel.
