  • Willem Velthoven with embroidered 404 - 

    For Picnic Network, I've made an embroidered 404 page. I hope you won't see it in function. But since we had to design and build the whole system at very short notice, it may happen sometimes:-)

I'm a designer, learner and cultural enterpreneur. Founding partner at Mediamatic Amsterdam. I like developing social networks. Btw, did you check the People you should know page?

At Mediamatic foundation, a cultural institution in Amsterdam, I'm resposible for general management, curatorial strategy and art direction. At he moment i'm very happy with the success of our El HEMA project. At Picnic 07 we present the RFID Hacking camp, Play with your Tag and The Girlfriend Experience.
