Metastasis or Metastaseis (“dialectic transformations”), is an orchestral work by Iannis Xenakis, a Greek composer-architect and a major figure in the postwar development of musical modernism worldwide. He is particularly remembered for the pioneering use of stochastic mathematical techniques in his compositions, including probability (Maxwell-Boltzmann kinetic theory of gases, aleatory distribution of points on a plane, minimal constraints, Gaussian distribution, Markov chains), game theory, group theory, Boolean algebra and Brownian motion.
Metastasis was inspired by Einstein’s view of time (a function of matter & energy) and structured on mathematical ideas by Xenakis’s colleague Le Corbusier. The 1st and 3rd movements don’t have a melodic theme to hold them together, but rather depend on the strength of this conceptualization of time. The 2nd movement does have some sort of melodic element. A fragment of a 12-tone row is used, with durations based on the Fibonacci sequence (1,1,2,3,5,8,13,21,34…)
The preliminary sketch for Metastasis was in graphic notation looking more like a blueprint than a musical score, showing graphs of mass motion and glissandi like structural beams of the piece, with sound frequencies on one axis and time on the other. In this video I tried to display this by presenting the frequency spectrum (0-20.000Hz) of the piece and how Xenakis actually “drew” music.

Overrall concept is: By connecting place and the lighting system interactivery, put the building into the broad experience happens the area. Hence make the building from Background to Foreground of the life.
1)Twitter Pulse/ Mood
Con: Currently speed of the flow of related #tag is quite slow.
Pulse(with speed of flow) with color of mood(of the content)?
2)Light message for locals
Package of light.
2-1)
By Slit-scaning a picture from a phone. This effect adds time-axis to a picture. User may draw a pattern onto paper and take a shot of it.
Slit-scanning method creates linear pattern and a bit boring. So how about adding ‘twist’ effect? (by whom?)
2-2)
Audio message. Lighting visualizes the audio as histogram? User should be on site and wait a bit for the light is going to morph to the audio message.
a)QR code is sent. Receiver shall go visit the museum facade and show QR code on mobile phone’s screen and put it at scanner. Then audio (just for around the scanner) and histogram-animation( on the facade LED) appears.
3)Useful lighting
should include ‘unexpected encounter’ and/or ‘familiar stranger’ function into the app
->Simplified.
Light culumn corresond to the proole nearby
When you simile at the building, the light column arise.(Distance from the building arise)
