This is the first available on-line demo. Click here to launch the demo in your web browser. It is a simplified version of an interactive installation we have designed for last year's exhibition of our multimedia school in Paris. However, be patient since there are some images to load... A complete description of the installation has been published at the Virtual System and Multimedia conference last year (download the paper here). The virtual creature is an oracle in the "matrix", so she generaly answers in a pseudo-philosophical and enigmatic way to questions (like in the movie). This demonstration is based on a pure reactive implementation, that is without any "memory". This is the simplest way to implement an application with the EVA technology.
