An eye-popping music video for Willow's track "Sweater" uses projection mapping and elaborate choreography to create cities, oceans, and galaxies. Thanks to a treadmill built into the floor, the singer appears to stride through city streets and country roads, and the shifting camera perspective brings movement to a static environment, whether it's sailing across an ocean or falling through a wormhole. 

Belgium-based video artist Filip Sterckx, the video's director, shares some outtakes from the shoot, below, in which the singer valiantly negotiates the tricky treadmill and other transitions.
