Guenter Richter, the person behind "Masters Of Light", operates with old but bright Leitz slide machines and overhead projectors. Images with a diameter of up to 10 m can be projected up to a distance of 20 m using different lenses.
The effect is created with special colourful dyes which are used to tint oil and water. This liquid is then moved using motors and pumps. All the technical installations have been developed and designed by Guenter Richter.
All slide machines operate with 220 V DC, most of the light bulbs are 250 W. A stand of about 2 m in height is needed for the performance. 

"Masters Of Light" is exclusively technologically "old skool": no pixels, no bytes, no laptop.
