Some people spend five days building a deck. Others spend five days creating a marble masterpiece that unleashes 19,000 marbles in one glorious avalanche.
Jelle’s Marble Runs has assembled what may be one of the most mesmerizing Gravitrax creations ever, combining Gravitrax and Xyloba components into a sprawling marble run that culminates in enormous pixel-art fields made entirely of hand-placed marbles. Originally aiming for 15,000 marbles, Jelle kept counting… and counting… until the final total climbed past 19,000.
The video begins with timelapse of the five-day build before the real fun starts (1:29) as thousands of marbles race through the elaborate course, triggering an avalanche of color and motion that took days to prepare but only minutes to unfold. Check it out!
