Waldian
Waldian is a standalone, wall hanging sound and light fixture capable of playing a near infinite amount of melodic permutations over a predetermined musical scale, complemented by emerging light patterns from twelve separate LEDs spread across the sculpture. In technical terms, Waldian contains two oscillators, an envelope generator and a voltage controlled amplifier, all controlled by impulses from a network of logic gates akin to those of early computers. These impulses are essentially the nerves in the electronic ecosystem, deciding over pitch and amplitude changes as well as creating bursts of light to highlight the entrances of each note. Finally, there is a tube overdrive stage that creates harmonic and subharmonics based on how far away the two oscillators are from each other in frequency. Most parameters are customizable, such as the aforementioned pitch, amplitude and overdrive, but the responsiveness and envelope of the light bursts can also be adjusted, directly affecting the appearance of the light patterns.

Calculations, permutations and notations
LAb|au| developed a transdisciplinary and collaborative approach based on different artistic, scientific and theoretic methods, examining the transformation of architecture and spatio-temporal structures in accordance to the technological progress within a practice entitled ‘MetaDeSIGN’. Metadesign [ meta = information about information ] displays the theme of space-constructs relative to information processes – architecture as a code. It concerns the transposition of inFORMational processes in n-dimensional form.

In a twelve-tone composition, every note can be accounted for as being a member of the original series or one of its permutations, providing unity to the piece as a whole. Additionally, a twelve-tone series is a repository of intervals and can be seen as an outgrowth of atonal music with its emphasis on interval over chord or scale. The basic premises of twelve-tone music are as follows: 1- All twelve notes of the chromatic scale must occur; 2-No note can be repeated in the series until the other 11 notes of the chromatic scale have occurred (exceptions include direct repetition of a note, trills, and tremolos); 3-The series can be inverted, retrograded, and the inversion can be retrograded; 4-The order of notes in a series remains fixed, without reordering.
