In the weekend of 11-12 March 2006 was the Crystalpunk workshop for soft architecture in Utrecht (NL) with a lot of cool speaker: Mario Campanella, Mirjam Struppek, Adam Somlai-Fischer, Pablo Miranda Carranza, Nicolas Nova, Jelle Feringa and me with z25.org :).
I presented the RFID installation Dat-a, that I developed together with z25.org.
The slides from my presentation can be found here: dat-a_pres.pdf
