Re-programmed Art: An Open Manifesto is an action research project that explored the impact of methods and approaches linked to open source hardware and software on the field of art. The aim was to produce a number of physical and technological artefacts whose information and implementation specifications are publicly released under free licenses.The group of digital artists and designers involved in the project had the task of re-programming a number of works by Gruppo T, the pioneering group at the forefront of the Italian art movement known as Arte Programmata. In the late 1950s and early 1960s, these artists developed a ground-breaking vision of art as reproducible, participatory and interactive, and created prototypes based on the use of algorithms and technology which were designed to be reproduced as series of constantly changing artefacts. The concept of 're-programming' is about more than just reconstructing the original works, understanding what they were made of and how they were made, and the algorithms used to incorporate an element of chance. It means bringing them to life again, reworked using new materials and technology. Pieces by Gruppo T were thus transformed into new, open artworks that can be reproduced, expanded on and completed by other users: a vibrant tribute to an original, innovative movement that occupied the no man's land between art and design.
