When you click your computer’s mouse or type on the keyboard, what exactly is going on inside the computer itself? What controls the information flow in and out, and what exactly is juggling the human-written programs, the memory, and the billions of instructions being processed every second?

DYSKOGRAF is a graphic disk reader. Each disc is created by visitors to the installation by way of felt tip pens provided for their use. The mechanism then reads the disk, translating the drawing into a musical sequence.
The installation is above all a tool, which allows the creation of musical sequences in an intuitive way. The notion of a loop, closely linked to electronic music, is represented here by the cycle of the disk. The disk passes indefinitely in front of a camera fixed onto an arm. This substitution for the needle converts the drawing into sound by way of a specific application program (software). Through this system, the sequential ordering of music is learnt in a playful way, at the same time creating a unique object, souvenir of the musical composition.
The numeric world is a world of binary choice. The object of DYSKOGRAF is to give room again for accidents in numeric creation, accidents that often favour creativity.

How does the internet work?! The World Science Festival explains it…
The video lets you ride shotgun with a packet of data—one of trillions involved in the trillions of Internet interactions that happen every second. Look deep beneath the surface of the most basic Internet transaction, and follow the packet as it flows from your fingertips, through circuits, wires, and cables, to a host server, and then back again, all in less than a second.
