I like your Java animation!! Tony Am 28.03.2012 um 02:12 schrieb Tony Phillips: (I'm not sure exactly which picture you wanted; that space in your email was blank. The images are not numbered, but perhaps you can use the page number and "top, middle, ..." for identification.) T. Dear Tony, wow, that was an incredibly fast reply (one should not go to bed before 3am, in europe). Thanks a lot for the permission, this is extremely helpful. I mean the pictures of the "real" machine Page 4 Top: http://www.ams.org/samplings/feature-column/fcarc-cusp4 This is http://www.ams.org/images/cat-machine1.gif http://www.ams.org/images/cat-mach2small.gif I use it on page 12 of the article (attached). If you have similar pictures in higher res this would also be great. The message that the picture should transport in my article is that although the CM captures an abstract idea you can actually build it. BTW. yesterday I was browsing through your "What's new" website  http://www.math.sunysb.edu/~tony/whatsnew/index.html and discovered a few nice parallels. 1.) I saw that Bill Casselmann sometimes writes in that column. Bill was also present at the conference in Dresden last summer which is the origin of the book project for which I write the article. ( http://www.math.tu-dresden.de/DGfGG-2011/ ). 2) I have a german internet Portal Mathe-Vital (www.mathe-vital.de) where I collect Java simulations (essentially all of them made with CInderella (www.cinderella.de) ) that explain different topics of math. Some of them have quite an overlap with the topics on the "What's new" site. You might in particular like Plant growth http://www-m10.ma.tum.de/bin/view/MatheVital/Botany/WebHome or Music (for this you need a fast computer and a java sound bank) http://www-m10.ma.tum.de/bin/view/MatheVital/Music/WebHome But there are also many related to "real university mathematics". like http://www-m10.ma.tum.de/bin/view/MatheVital/LinAlg1/WebHome You might also like the article http://www.combinatorics.org/Volume_16/PDF/v16i2r12.pdf on Hyperbolization of Euclidean Ornaments. At least Bill liked it :-) Thanks a lot for your help and best regards from Munich Jürgen Here is an attachment of the model article (in case it did not work in the last e-mail): [ Part 2.2, Application/PDF 2.5MB. ] [ Unable to print this part. ] [ Part 2.3: "Attached Text" ] -------------------------------------- Prof. Jürgen Richter-Gebert Geometrie und Visualisierung Zentrum Mathematik --- TU München Boltzmannstr. 3 85747 Garching bei München Tel: 089/28918354, Sekr: 089/28918359 e-mail: richter@ma.tum.de
