YouTube user Ben Tardif has spent the last three years building a magical marble mountain. The kinetic sculpture is complete with a miniature roller coaster, half pipe, and ski jump, as well as tiny versions of real-life landmarks like the Great Wall of China and Times Square. Constructed out of 25 segments, Tardif’s Magic Mountain has 32 separate pathways for marbles to roll down.

But while Tardif’s Marble Mountain is impressive, it’s not done yet. “Every element is themed (or will be upon completion) to an aspect of my life or to something that I find interesting,” explains Tardif. “It took three years to get to this point of being able to turn it on and watch it go, and I will continue to work on it and get it fully completed.” Check out the first working version of Tardif’s kinetic sculpture above, and keep your eyes peeled for more additions.
