ASYNCHRONOUS CIRCUITS
2008-11-06 20:14:00 KünstlerInnen: Barnaby Hosking (GB), Judith Fegerl (A)"Die Wahrnehmung natürlicher oder vermeintlich natürlicher Phänomene im Spannungsfeld von Ästhetik und Epistemologie bildet den Untersuchungsgegenstand für Barnaby Hosking und Judith Fegerl. Beide de- und rekonstruieren ästhetische Regelsysteme, unterwandern die von ihnen analysierten Bildsysteme, indem sie den eigenen Output operativ einbinden und mit dem System rückkoppeln. Dieses Wechselspiel der Rückkoppelungen und Interferenzen von Medium und Wahrnehmung, von medialem und mentalem Apparat, wirft die Frage nach der Konstruktion unserer Wirklichkeiten, unseren Weisen der Welterzeugung auf. Dabei rekurriert Hosking auf das Kunstschöne des Landschaftsbilds, Fegerl auf Modelle der Mathematisierung von Raum und Zeit. Beide fokussieren in ihren Arbeiten instrumentell gestützte visuelle Systeme, Hosking optische Systeme wie den Polarisationsspiegel, Fegerl die Regien des wissenschaftlichen Bildes. Wenn Hosking in weiterer Folge mit ...

What is the technical reason for not breaking

Giant Volume Meter!
2008-03-05 08:07:00 Wow, check out this GIANT volume meter! So cool lookin’~ Looks like it’s some type of microcontroller with bunch of replays… Looks pretty simple to build… (the controls i mean) “Volumen”, a giant graphic equalizer built by Argentinian artist, Sergio Avello relays the ambient urban noise levels around the Redgaleria in Buenos Aires. Pretty ...
