  * 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

  * 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.

=== 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:
