Meet Merlot: a beautiful kinetic wooden sculpture that mesmerizes you with a kaleidoscopic effect. Merlot does not make a whole lot of noise. As you can see in the below video, Merlot displays large and small stemless wine glasses as it rotates. Fully wound, it moves for 2.5 hours.
Derek Hugger has a bunch of other kinetic sculptures showcased on his site. The good news is you can buy the plans to build your own. More info is available here.
