“Dieter Liedtke is ideology-free positive energy, quintessentially
creative and an artwork himself. Leonardo da Vinci has found
a successor in him.”

”The positive energy of the inventor-artist and Leonardo da
Vinci of contemporary art, Dieter Liedtke, can be experienced
by any visitor of the exhibition by means of his work. His work,
theory and concepts are revolutionary, contagious and point
out new ways to a humane society to art as well as science.“
“Today, access to creativity is only possible via images, because
it is image sequences that the human mind works with. The archetype
of every vision of the future is the vision, the dream, the
connection of non-existing realities. The path from the future
to the present is only possible by using the visual language of
art. It makes people visionary, enabling them to experience the
processes so far unnoticed and understand them. To trigger
this potential in people who have no special equipment for
it, the Art Formula is kept simple in terms of optical visibility: it is
based on the evolution of innovations...“
