Tol Tol Tol was a project about relationships among space, sound and color, during a choice of paths in a context of many options. We like using the concept of "virtual ecosystem" because it's a system composed of many interactions and each one changes in an orderly way. We oppose this concept to the concept of "virtual stage", where the stage designer disposes some objects with behaviours to be visited by the user.

Tol tol tol was supported by IUA of UPF and was advised by Narcís Parés. It was awarded in 1999 with Premi Möbius Barcelona Multimèdia to the best artistic and cultural on-line application.

The user finds a VRML world with a 3D maze build by modules wich looks like a bubbles.When the user enters into the maze he takes up a bubble and this bubble plays a sound.

The user starts a symbiotic relationship with the maze. With this sound, the maze composes in a real time a melody playing other adjacent bubbles. This melody defines a path which the user must follow.

If the user leaves the path he will generate a new sound out of the melody and the balance will be broken. Some bubbles will change their place to rebuild a new more balanced space shape.

In consequence, the maze will change its shape, colour and sound in an irreversible way.

When the user goes out from the maze, the system plays a long melody made up of all short melodies generated during the navigation. This is the musical topography of its journey. You can listen now one exemple of that.
