Our vision system tries to get the real colour of subjects autonomous, while calculating the lighting colour off- like the white balance of a camera. With more than one lighting colour our vision system is overstrained. Here white and green light is directed on a white area. When you are holding your hand some centimetres over the area, it casts two shadows- from each lamp one.

By turning the disks, appears an optical mixture of the colours, which are attractive and stimulating. Also, aspects of the theory of colours are experienced by the five colour circles

Here comes a funny optical module, which you absolutely have to hold in different amounts, so the youngest have their fun too! If you stay really close to the mirror, you can see your face clearly bigger.

On all of the three sides of a narrow pillar are in each case three triple mirrors in different orientations. Like the “cat eye”- reflector they shade the incoming light in the same direction back, so you can see yourself in the middle of the triple mirror- independent from where you are looking into it.

A concave mirror creates enlarged, virtual pictures. A cylinder glass shows this effect just in one direction: the image is contorted in the horizontal direction, that means the height stays the same, but because of the extreme curvature changes the breadth.

Mirrors with an undulatory surface distort a picture in a special sage: Zones which are arched (concave) to the inside, that enlarge, switch with convex outside curvatures. The picture changes with the distance to the mirror.

Our shadow: A daily, reliable attendant, which participates all of our movements easily. In this big exhibit the proverb “Jumping over the own shadow”, gets a new meaning. 

This first inconspicuous seeming exhibit moves you into its spell after the first perspective. You look through one of the openings in a sheer endless mirror walk and will be amazed about the numbers of your own mirror image.

Do just special letters are turned? On the upper area lays a movable plate with several words in black and coloured letters. When the plate is moved from one side to another and the text is watched through the cylinder, the black words are readable, but the coloured are upside down.

The Word Kaleidoscope arrived out of the Hellenic and means as many as “see beautiful”. Again, and again appear new pictures for the “seer” in this pivoted and aesthetic designed exhibit.

A big, horizontal laying kaleidoscope is stored in eye level. The surrounding area serves as picture template from which a small section- turned and mirrored again and again- split up to a limitless seeming picture. 

A tricky illusion with two mirrors. The concave mirrors are facing each other. In the lower mirror is a subject inserted.  Uppermost is a virtual picture produced, which is viewable from different perspectives.

To write the own name in sand is more a relaxed activity. Though it is required, that the text is readable in the cylindrical mirror in the middle. To consider the mirror image thereby is so irritating, that the drawing from a straight line itself is a competition!

From the view of the drawer the mirror reverses the front and the aft, but not left and right. This makes it difficult to follow the given line. Also, you know in which direction the form goes, the hand does not perform the intended movement.

An infinite number of mirrors!  No matter if you look upwards or downwards, to the left or to the right: reflections of reflections of reflections everywhere around — and yourself right in the middle x times.

Lapping grids with the same division are twisted against each other. By printing, watching TV, scanning and other image creating grid procedures, occur the Moiré effects.

Behind a half permeable mirror is a camera, which cannot be seen, because of the mirrored glass cover. A monitor shows the from the camera provided picture. At the push of a button the area behind the mirror is lightened, so the half permeability of the mirror and the camera can be seen.

To mix faces can create very funny and astonishing pictures. In the computer technology it is named “Morphing”.

Three wheels are installed side by side, and a third in the inside is covered with a foil in a different colour: Cyan, Magenta and yellow. Those three colours form the basic colours of the subtractive colour mixing, which is for example used in inkjet printers.

A simple mirror apparent interchanges left and right, the view is “back- to front”. Two mirrors, which stay in a right angle to each other, reflect the mirror image again: so, it appears right.

We all know the kaleidoscope as a pipe with three mirrors, where you can watch colourful snippets or liquids. Here one to two persons can stand in the middle of the mirror triangle and watch the own mirror image endless.

Here you are in the centre- enveloped by a big bubble. Around you billows a dedicate entity, which shimmers in all rainbow colours.
