Media Files === symmetry synchronisation === Gert 20120118 * the "fancy" Alhambra walkthrough: http://www.saudiaramcoworld.com/issue/200604/alhambra/tour.htm (the other one seems to coarse) Mathias Wednesday * Most amazing Busby Berkeley choreography with many shots from the top as inspiration for audience pattern choreography * http://www.youtube.com/watch?v=kIO9y1xMPIA * All possible polygon constructions, incl. alternative 17-gon * http://www.youtube.com/watch?v=LBgIWQcC6lM&feature=related * crude but complete set of wallpaper group transformation animations * http://clowder.net/hop/17walppr/17walppr.html Gert 20120118 * A page containing a VRML model of the alhambra: http://www.amorphous-constructions.com/alhambraVRML.html (also in dropbox) * Russ found a page that actually has the Goldberg Variation Score available: http://www.jsbach.net/midi/midi_goldbergvariations.html * Another Room Modes calculator with some pictures that help understanding (and an english units converter): http://www.mcsquared.com/metricmodes.htm * Another Chladni DIY guide: http://www.make-digital.com/make/vol16/?pg=128#pg128 * Project page set up at: http://symmetry.pen.io * username is symmetry. send mail to gert@test.at for the password Gert 20120117 * A link to a Chladni Setup: http://www.instructables.com/id/Mechanical-Wave-Driver-for-Chladni-Plate/?ALLSTEPS Mathias Tuesday * What is it like to have an understanding of very advanced mathematics? http://www.quora.com/What-is-it-like-to-have-an-understanding-of-very-advanced-mathematics * Nice vector based presentation platform. Vector format based. Potentially good to draw a lot of our individual content together. http://prezi.com/ Gert 20120116 * A Risset Rythm SC Patch: http://swiki.hfbk-hamburg.de:8888/MusicTechnology/826 * Cymatics with fluid and regular speaker. looks a little makeshift, tho: http://www.youtube.com/watch?v=6NGJGfuIVfQ Marcus on 20120115 * This is quite a fun java app for generating examples of the 17 wallpaper groups http://escher.epfl.ch/escher/ === late adds by Gert 20120114 === * A little thing I just found: http://www.openprocessing.org/visuals/?visualID=1261 * Inkscape, the open source svg editor supports all 17 symmetries: http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Tiles-Symmetries.html * Inkscape is scriptable via python, as I take: http://wiki.inkscape.org/wiki/index.php/PythonEffectTutorial. * May be usable for some step-by-step processing of live video footage? I'm espcially happy about the room-modes & schuman references, since they close the circle to something we already discussed and tried (not too successfully me thinketh) @ ICA & waves. it's a lets make it work moment :) I tried to compile scopeshapes for Intel, but failed so far. how would we translate the oscilloscope output? I'll bring two Wiimotes, but rather than waving them around i was hoping to use the IR input. lets fix diodes to Marcus' hands for his Cello performance :) OSC enabled version avlbl. [...] I keep these very brief, essentially list of links. === A few notes from skype call with Gert, Nik, Mathias 20111216 === * A Computational Model for Periodic Pattern Perception Based on Frieze and Wallpaper Groups * http://www.ri.cmu.edu/pub_files/pub4/liu_yanxi_2004_1/liu_yanxi_2004_1.pdf * This is a paper by Stephen Hyde discussing some of the ideas that have been influencing Mathias' recent work on geometry and structure * http://people.physics.anu.edu.au/~sth110/10_1_ArchThRev.pdf * http://physics.anu.edu.au/appmaths/Profile.php?ID=70 * One of the things mentioned in the above paper is the Gavrog project - Unified Tiling Theory. The background presentations at the bottom of the page are very useful * http://gavrog.sourceforge.net/ * Current generative work found by Nik * http://roberthodgin.com/crystalline/ === A few notes from meeting with Marcus, Richard, Mathias 20111221 & 20120112=== * Brian Sanderson's Pattern Recognition Algorithm (aka. the decision tree) * http://www.math.toronto.edu/drorbn/Gallery/Symmetry/Tilings/Sanderson/index.html * The structure of the evening presentation follows an imaginary walk through the Alhambra - as the pattern groups progress, so will we. * The group of 7 frieze pattern of linear tiling * http://en.wikipedia.org/wiki/Frieze_group * The group of 17 wallpaper patterns of tilings of the plane * http://en.wikipedia.org/wiki/Wallpaper_group * It is possible to 'pattern' a room acoustically using a standing sound wave, also called Room Modes. The Hoffmann Building is 19.7 x 15.3 x 15.5m * http://www.marktaw.com/recording/Acoustics/RoomModeStandingWaveCalcu.html * http://en.wikipedia.org/wiki/Room_modes * Schumann Resonances are the Room Modes of planet earth's electromagnetic field * http://en.wikipedia.org/wiki/Schumann_resonances * A very good SciArt collaboration based on Schumann resonances * http://www.mitpressjournals.org/doi/abs/10.1162/096112104322750755 * http://dl.dropbox.com/u/18987631/FTS%20Symmetry/13.1first.pdf * A recent project to allow public domain access to Goldberg Variations. The Musescore edition has been announced for early 2012, so could be used by us, if we get in touch * http://www.opengoldbergvariations.org/ * http://musescore.org/en/node/9622 * http://www.kickstarter.com/projects/293573191/open-goldberg-variations-setting-bach-free * More Goldberg Variations notations, recordings, midi * http://imslp.org/wiki/Goldberg-Variationen,_BWV_988_(Bach,_Johann_Sebastian) * Marcus's research builds a lot on prime numbers and prime number tools like prime zeta functions and Fermat primes * http://en.wikipedia.org/wiki/Prime_zeta_function * http://en.wikipedia.org/wiki/Fermat_number * Xenakis Nomos Alpha uses algebra and geomerty in its composition/construction * http://en.wikipedia.org/wiki/Nomos_Alpha * A compass and straight edge construction of the 17-gon. Interestingly a 7-gon cannot be constructed using compass & se. * http://www.youtube.com/watch?gl=GB&v=ZMxcuiSxzQs === From emails from Russ to Mathias === OK just FWDing info of the stuff im interested in and have that maybe good for snape!? its totally about symmetry! here is the software i spoke off: * http://www.chrismeighan.com/projects/scopeshapes if we could make these .DXF files we could have text+ i have this device that can generate much better material than in this video: * http://www.youtube.com/watch?v=Ypn9JJXSl7w&list=UUnG85Ity-dN4EjWxhqEBsSw&index=5&feature=plcp i dont know of it will be in the UK by the time of the residency, but i have one of these due: * http://www.youtube.com/watch?v=Q5pwtncsNW8 * http://www.youtube.com/watch?feature=endscreen&v=u33VMNZRaiQ Please fill all the letters into the box to prove you're human.
