EVA Holographic Ghost

It has been a long time since my last post. We have worked a lot on a multimedia exhibition which takes place at the Leonard de Vinci University until the end of March ( In the next few posts, I will describe some of the installations we have designed with our students. The first one is an holographic artificial creature based on the EVA design (Evolutionary Virtual Agent). Imagine some sort of woman ghost floating in the air just in front of you. She is dancing slowly in the air. This installation uses a simple but efficient system composed of turning cords and holographic paper. The result is amazing as you can see on the image considering the simplicity of this installation.

This installation has been designed by the french artist Cyril Vachez ( This system recalls a number of simple optical devices that were invented in the nineteenth century like the ZooTrope created by William Horner in 1833. The lower picture has been taken at high speed to be able to see the principle of this system. It is mainly composed of two parts. The first part includes a set of holographic cords, an electric engine with a speed variator, and a roller skate wheel fixed on the ceiling. The second part includes a PC computer running the artificial creature movie or program, and a video projector. This "holographic ghost" is used to introduce EVA to the visitor, just before entering the second room where he is able to interact with her. I will describe this other installation in the next post.
