First of all, let me say that Transmediale did a really great job at accommodating the needs of 70+ hackers and their tech-works, providing us with an 'open pantry' of tech equipment, catering and tech support. Personally, I hacked my way into the Hackathon (I was not invited but hacked in via a twitter backdoor) so I am extra happy to be part of the event. It was a very exhausting but interesting and fun experience. However the fact that the work I created became part of the main Transmediale exhibition, which finally became a marketplace is a dynamic that is easily overlooked but that should be considered. Not in the first place because the audience needed an entrance ticket to go and see the exhibition, yet the (invited) artists did not get payed, but because the dynamic between the internet or digital arts and money or economies is one that is evolving quite rapidly.
