 +   * Project page set up at: http://symmetry.pen.io

 +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.

 +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

 +This is quite a fun java app for generating examples of the 17 wallpaper groups

 +=== 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

 +
 +=== 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.

 +
 +=== 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:
 +

 +
 +
 +i dont know of it will be in the UK by the time of the residency, but i have one of these due:
