hi,

i am a architect/designer and work in beijing. Me and my friend won the red-dot award in 2010 for a clock
clock
which by now is well know... I have been developing the mechanism of the clock for the last 2 years.. I have developed most of the electronics and the base mechanism of the clock... but i am stuck with not having a good mechanism to keep the blades equidistant while functioning....

the thing is that the blades for to be kept equidistant all the time...no the japanese fan mechanism wont work.. ( i have developed a mechanism but it is far too complex )

Anybody willing to help and coming up with a good solution can partner with us in production...

thanks...
