Mathias Thursday
- Wallpaper group SVG diagrams
- Collection of text and projects of Edmund Harris & students at the University of Arkansas
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
- All possible polygon constructions, incl. alternative 17-gon
- crude but complete set of wallpaper group transformation animations
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.

- 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
- This is a paper by Stephen Hyde discussing some of the ideas that have been influencing Mathias' recent work on geometry and structure
- 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
- 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)
- 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
- The group of 17 wallpaper patterns of tilings of the plane
- 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
- Schumann Resonances are the Room Modes of planet earth's electromagnetic field
- A very good SciArt collaboration based on Schumann resonances
- 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
- 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
- Xenakis Nomos Alpha uses algebra and geomerty in its composition/construction
- 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:
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:
