    Okaya/Rodan DK23 dekatron do-hickie flashing all 4 patterns, selectable by pushing the little button up front. Patterns are (1) Standard Pendulum, (2) Watch Balance [looks jumpy here due to video frame rate, but much smoother in real life], (3) Jellyfish, and (4) Radar. Much more fun than a simple spinner ! All the patterns slowly precess clockwise. Safe too. Runs from either 12VDC or 9VAC (50 or 60Hz).
