rhombic dodecahedron balloon

Here is the design of the rhombic dodecahedron that I promised for a long time. Since it's tricky to follow I have a diagram below that may help you create it. The structure probably looks best when you use one to two inch bubbles rather than the longer ones I used in the video.*.7.8*.9.14

Here is the psuedo-gauss code for this design and the pattern. Probably I need to include a sequence of diagrams to really make this dodecahedron. I find these useful too. The diagrams perhaps are more useful in the design phase rather than the construction phase....

The * is there to indicate a bit of a tricky spot. For these you must pull the balloon through a square. It's not that tough on the balloon but it is important to know that it must come through the square an not just wrap around--the geometry changes when the balloon is complete and it would come apart otherwise.

Also note that 0 is mentioned but it is not in the diagram. The reason for this is that it would clutter up the diagram (it would turn the graph into a non-planar graph). The 0 point represents the centre of the dodecahedron.

Babel fish may not have done a perfect job on that but I'm glad you found the post useful.

Actually, I missed "forever multicolored!" and your blogger name is "second round".

Well I hope you have a multicolored second round whether that's drinks or whatever :)
