I just ran across a demo of what was called “Finger QiGong” on youtube.
It seems to be a form of contact juggling (this example, not QiGong, of course). It’s rather cool. Rather than the 3 inch/ 75 mm speres that seem to be common for multiball contact, they look like about 2 inch or 5 cm spheres, and they are rolling pretty fast. Check it out.
Another interesting part is that the balls seem to have chimes in them, adding an almost music element.
Another video in the series:
There seem to be a few videos of this type, so search youtube, and see what you find. If you find anything particularly good, post a link in the comments!
