Professional domino artist Hevesh5 does a lot of great domino builds, but this colorful triple spiral is both beautiful and relaxing to watch.
Quoth Hevesh5:
I spent 25 hours spread over 8 days building this massive triple spiral structure with 15,000 dominoes. Subscribe for my best project yet :) Worked flawlessly with no breaks! For proof, watch this structure build itself in REVERSE! Pretty sure this is an American record for longest domino speedwall too :)
