An extraordinarily complex, hand-cranked conveyer belt that uses the rattle and shuffle of its mechanism along with the click and swish of 2000 cascading marbles to create notes and rhythms.

Built by Swedish musician Martin Molin, it’s actually just part of Marble Machine X – a much larger project he’s been working on since completing his first such contraption – the Wintergatan in 2016.

Colibri – an elegant kinetic sculpture by Derek Hugger that mimics the  flight of the hummingbird. Sez he:

Every element of motion has been completely mechanized, from the beating wings to the flaring tail. Intricate systems of linkages and cams bring the sculpture to life with a continuous flow of meticulously timed articulations. As each mechanism has been linked to the next, Colibri cycles through its complete range of motions by the simple turn of a crank. This project took me roughly 700 hours and contains about 400 parts.

The Tread 1 from Californian watch manufacturer DEVON is a busy little piece of wrist candy. Official retailer Watchismo sez:

The exposed movement is a mesmerizing display of the patented interwoven system of conveyor belts. This series of belts includes critical elements that allow the optical recognition system to know every belt position at all times.

The Tread 1 Watch features four internal 2-micron thin belts that spin within the case to display the time.  It’s powered by a lithium polymer rechargeable cell that is charged by wireless induction.

Shipping is free.

The watch, on the other hand, costs between $17,500 and $19,500 depending on finish.
