Put on the earphones and start turning the pages of the book. The book relates the story of a troubadour as he goes through a medieval castle playing his harp. The aim of this acoustic exhibit is to help visitors understand that the sounds we hear are influenced by the space we are in and the objects that surround us. On each page of the book, you find yourself in a difference space with different acoustic properties.

Morphing is a process often used in films and animations and is one of the most impressive digital image processing techniques. It allows one image to be transformed into another with continuous distortion. Morph your face and discover your other self!

Digital storage and transmission of pictures has become common practice, yet the general public still knows little about the procedures used to convert an analog picture into a digital picture. In addition, although digital technologies offer many advantages, in particular when it comes to the lack of degradation when recopying or transmitting pictures, the problem of the quantity of data needed remains a tricky one to resolve. This is why an understanding of compression techniques is so important.

3D graphics are digital models generated in the circuits of a computer. The technique, first produced in research laboratories for the purposes of visualising space for flight simulators, is now widely used in the fields of science, medicine, industry, entertainment and art. Be they precisely recorded and modelled renderings of real objects and spaces, results of mathematical computations or the product of a computer artist’s imagination, such pictures offer us novel virtual worlds that can be manipulated and with which we can interact.

Do you find it difficult to understand the terms "oscillatory nature" and "mechanical nature" of a sound wave? Is it hard to explain why drinking glasses hum when a tenor sings? Learn about sound waves and their properties by interacting with this unique exhibit. Strike the drum membrane; what do you observe?

Can we hear everything? Learn about the frequencies of the sound spectrum that humans and animals can perceive through a graphic illustration. Aim at the centre of an image with the joystick, listen and look at the area of the sound spectrum that lights up. What do you observe?

Did you know that white light can be created by combining three different light sources: red, blue and green? Through this unique application, try to create white light or light of any other color. Change the color of various objects by placing colored filters and masks in front of light sources. Study the results and enjoy making colors.

Lighting plays an important part in setting scenes. This is the case in the theatre, for instance, where it is used to create different atmospheres. Lighting techniques in computer graphics are based on the rules of traditional photography. On a virtual cinema set, a photography director takes precise parameters into account to create nuances that yield the desired effect. Good lighting should heighten elements of the decor and recreate the right mood and atmosphere.

Retinal persistence is a characteristic of the human eye that gives us the illusion of motion when we watch a cartoon, for example. The cells in the retina retain the memory of a picture for a tenth of a second after we’ve seen it. So when a series of images is flashed by rapidly, at the rate of 24 per second, each picture is kept in mind before the next picture appears and so the eye is unable to see the blanks between two consecutive pictures.

Color description is subjective as it is based on the perception of the human visual system. The retina, located at the back of the eye, is covered with cones; these are cells sensitive to colored light, but they are not all sensitive to the same colors. Some react to red, others to green or blue. Our vision of colors varies, especially when the eye is tired. If we stare at a red
