Four-Dimensional Zoetropes

Wow.   I totally forgot about this.   Well, it was 14 years ago, after all…

The original *thing* of this thing no longer exists:

http://www.thingiverse.com/thing:82691   (But, check out the Thingiverse’s Httpd 404: Not Found page — It is listed among the awesome Httpd 404: Not Found pages on the Internet)

The header comments of the OpenSCAD file for this thing are as follows:

/*
Nick Pullen, May 2013
Description:

Here are the parts for 3 dodecahedrons, that once magnet are installed in the recesses will self assemble into complete objects. Due to the spacing and polarity of the magnets, only parts of the same will fit together.

There is a video of the original idea that inspired me to design these: http://vimeo.com/44291046#at=0

And the Researchers’ site: http://bioselfassembly.net/

Instructions:

When installing the magnets, make sure all the left hole magnets are orientated the same polarity, and then the right hand hole make sure the polarity is reversed. I have used 3x1mm neo magnets off ebay, N35 they were called….

The SCAD is partly parametric, but have a play, I have commented on what the components are…

My builds are here:

They were done on PP3DP's and a LulzBot TAZ at the C-U Community Fab Lab

They got the attention of Skylar Tibbits of the MIT Self-Assembly Lab, who contacted me through the Thingiverse to remind me that

Arthur Olson, holds the patent on self-assembling polyhedra (of which your dodecahedron falls under). I’m guessing it is fine to print for your own interests or educational purposes, as long as it isn’t for profit or a business. google.com/patents/US8507778?cl=en

The last two pictures show the pieces loose in the box and then the box after closing up and shaking.  Order from chaos.   It appears to violate the Second Law of Thermodynamics.   Take that, Dean L. Overman!
