More details on heart-shaped gear assembly

I posted the other day about this amazing heart composed of moving gears.

At the time, I was quite uncertain about the material used. One commenter said that it was papercraft, and would appear to be correct.

I am told that the artist was a winner in a world karakuri contest back in 2005.


I see also that the artist has made a piece similar to the heart in the form of a cube. Video of the cube can be seen here if you have the right plug-in.

The artist, Haruki Nakamura, also does other forms of paper-craft including illustration, models, and impressive 3 dimensional tessellations.


See more from the artist on Haruki Nakamura's web site.

[ Thanks philsing and PINO! ]

Very nice! I can't play the video but it makes sense: if you can create any 3d set of gears that mesh and rotate, e.g. starting from a tetrahetral arrangement and adjusting gear sizes to allow free movement, then "all" you need to do next is project a cone from the object's centre and clip the cone at the object's desired outer skin. Should be able to make any convex and many concave shapes using this technique. The gears each have a cone of space extending to infinity in which they can be sure they won't collide with other gears.
