STEADYo

(vimeo link)

When we watch someone play with a yo-yo, we normally see the yo-yo move while the person is standing relatively still. Douglas Khozam reversed that view by using motion-tracking technology to make the yo-yo stationery while the operator does the moving around. Or, actually just the hands. The video really gets wild when it turns into a kaleidoscope! -via Laughing Squid
