Wave Block - Water Cube
(水立方) - kinetic sculpture
Please
check it out in youtube:

I
was inspired by Reuben Margolin's kinetic sculpture in Youtube and decided to
do one of my own.
The
wave block also resembles 2008 Beijing Olympics Opening ceremony, where the
wave like movements were created by hundreds of men pushing their blocks from underneath.
Although
the materials have nothing to do with water, its movement has the watery -
fluidic characteristics, hence I also call it Water Cube.
While
it is also describing two sine waves travelling in perpendicular, the driving mechanism
is totally different. This wave block is driven by ONE motor only. It is portable
and is self-contained inside a tall cookie jar. The 2 Sine waves are kept in
phase, hence the look is a bit different too.
Mechanically, "driven by one motor" implies that the complex interactions of the two sine waves adding together, as demonstrated by the "choreographed" movements of the 80 odd cubes, are all generated by one simple rotating action. If you wonder how it was done, I have left the cookie jar see-through for you to work out how...:)
The
equation:
f(x,y,t) = sin(x+wt)+sin(y+wt)
where:
"w" is the omega symbol.
w
= rad x m = m

rad s
