star twist crease pattern – original scan Originally uploaded by Origomi. this is the original scan of the star twist pattern I uploaded yesterday. It’s available in it’s final version here.

I created and uploaded a 3 page PDF of my star twist tessellation. It’s available for download here.

3.6.3.6 tessellation Originally uploaded by gila o. This is one of Gila O’s folds, which is a very nice example of one of Alex Bateman’s crease patterns. I just keep mentioning that guy today, probably because we had a few email exchanges- his work is kind of stuck in my head! Gila’s nifty stuff is at http://www.flickr.com/photos/87477835@N00/, she has some newly created folds there as well. check out some of her new work and let her know how cool it is!

First off, let me post a link to Alex’s new site- it’s www.papermosaics.co.uk. Not only does he have some great material there, but he also created a software program that generates tessellations- and it’s released under the GPL! (that means free forever, and allows derivative works that also must remain free). That’s an excellent thing, and really warms my heart. I’m a huge open source junkie and I always like to see people release things for free rather than trying to lock them up forever. Which leads me to my next point- Alex has an e-book available at his website, which he graciously provided a gratis copy of (thanks Alex!) It’s 3 pounds (which is about $5.40 US currently) and is a very nicely put together document, with a number of good introductory folds and lots of photos. I’m going to give some of them a go once I get a chance to put them on some thin paper. I’ve been trying to put together some simple PDF documents with diagrams and photos for a …

Alex Bateman wrote a swell perl script/app a while back called “Tess”, located here. it works quite well when you run it on a mac (providing you have the appropriate perl libraries installed from CPAN or elsewhere) but it really doesn’t run all that well on a windows PC, unless you go through a lot of setup. most of those steps are quite honestly a bit beyond most people, and since I have a commercial Perl compiler environment available to me I made a standalone application that runs on any windows PC. I’ve contacted Alex, in the hopes that I’ll be able to get him to post it on his site. I can’t accurately discover the licensing that he released his program under, so I’m not distributing it to anyone until I get some feedback from him. Here’s a screenshot of Tess running under windows: currently it still outputs to postscript, and I have no interest in changing that unless I’m sure the licensing supports me modifying anything. I’d probably integrate some sort of ps2pdf …
