Orbitando Satélites Orbitando Satélites Este Es Un Manual De Nuestro Taller, Orbitando Satélites
orbitando satélites orbitando satélites Este es un manual de nuestro taller, Orbitando satélites. En él queremos of“recer id”eas, recursos, técnicas e inspiración. Nuestro deseo es que sea utilizado también como guía para acercarnos a un procomún de cielo y ondas. Creemos que las tecnologías del espacio y del espectro electromagnético están impulsando una cultura limitada a intereses corporativos y de control, y en consecuencia, a un empobrecimiento de posibles matices y provocaciones en nuestras relaciones con los cielos y las frecuencias. Proponemos aquí algunas vías alternativas. A lo largo de cinco días, nos convertimos en una Agencia Espacial Autónoma Temporal . Este manual es una hoja d“e ruta de vuelo espacial y comunica”ciones no gubernamentales, no comerciales. Nuestro taller se articuló en tres bloques: Escucha y avistamiento aislamiento, se convierte en una poderosa metáfora.
