Check out my project at https://www.MobiusClock.com: A 3D WebGL Clock on a Möbius Strip that shows 24hr time on a 12hr face. The hour indicator follows the edge of the strip, thus must make 2 turns to return to its starting point, giving you a 24 hour clock. The minute and second indicators move along the middle of the strip and thus return to their starting points in only one turn. Has the ability to rotate!
