The Generator.x 2.0: Beyond the Screen workshop and exhibition kicks off in Berlin this Thursday. In addition to the workshop there will be two evenings of presentations open to the general public, intended to bring the topics of the workshop to a larger audience.

The presentations will take place at the Ballhaus Naunynstrasse, which is also the venue for the workshop. If you’re in Berlin I hope to see you there!

Generator.x 2.0: Presentations #1 - Thu 24 Jan, 19:00 - 21:00

• Keynote: Marius Watz [NO]
• Boris Müller [DE]
• Satoru Sugihara - Morphosis [JP/US]
• Eno Henze [DE]

Generator.x 2.0: Presentations #2 - Mon 28 Jan, 19:00 - 21:00

• Aram Bartholl [DE]
• David Dessens [FR/DE]
• Tim Schork - MESNE [DE/AUS]
• Skylar Tibbits - Theverymany [US]

See the Club Transmediale site for a full list of Generator.x 2.0 events. Documentation of the event will be posted on the Generator.x blog and Flickr group as it becomes available.

The AHO students needed a simple file uploader that would automatically transfer files from a local folder to a web server. The following application will simply watch a given folder and upload any files it contains to the FTP server. Note that it will delete the local copy upon successful upload, so be careful how you use it.

The code for the application is given below, but downloading the following ZIP will give you the required edtFTPj library files as well as a sample config file:

• FTPUploader.zip

Generator.x 2.0: Beyond the Screen
24 Jan -­ 2 Feb 2008, Ballhaus Naunynstrasse / [DAM] Berlin
Workshop / Exhibition / Performance

Leander Herzog: thePhysicalVertexBuffer

Generator.x in collaboration with Club Transmediale and [DAM] Berlin presents Generator.x 2.0: Beyond the screen, a workshop and exhibition about digital fabrication and generative systems.

Digital fabrication (also known as “fabbing”) represents the next step in the digital revolution. After years of virtualization, with machines and atoms being replaced by bits and software, we are coming full circle. Digital technologies like rapid prototyping, laser cutting and CNC milling now produce atoms from bits, eliminating many of the limitations of industrial production processes. Once prohibitively expensive, such technologies are becoming increasingly accessible, pointing to a future where mass customization and manufacturing-on-demand may be real alternatives to mass production.

For artists and designers working with generative systems, digital fabrication opens the door to a range of new expressions beyond the limits of virtual space. Parametric models apply computational strategies to the analysis and synthesis of space, producing structures and surfaces of great complexity. Through fabbing these forms may be rendered tangible, even tactile.

Call for participants

We are looking for 15 artists, designers and architects who have an existing practice based on generative systems and custom software, and who are interested in investigating physical formats through digital fabrication. The workshop will be practical in nature, and will produce a selection of works that will be included in the exhibition at [DAM]. Participants will have access to an on-site laser cutter, and an introduction to this technology will be part of the workshop.

The workshop is free of charge, but we will not be able to provide support for travel or accomodation. Participants are expected to have experience with programming software that will allow them to produce work suitable for production, such as Processing, VVVV or any other system capable of producing vector output. Previous experience with laser cutting or digital fabrication technologies is a bonus, but not a requirement.

Applications must be in PDF format and should including a CV and a short statement of intent, describing why you want to participate in the workshop and how fabbing relates to your existing practice. You should include a maximum of 5 images of relevant work, with a total file size of 2 megabytes. Feel free to provide links to web sites containing documentation such as videos or downloadable software, but please don’t send such content by email.

Please submit applications by email to generatorx [at] clubtransmediale.de. The deadline for application is December 21, 2007, accepted participants will be notified at the beginning of January 2008.
