it’s simply no longer enough. You really need to offer more.

And that’s only possible by making extensive use of technology.

Strictly speaking, what we do is highly specialised machine

building. One of our latest illusions, teleportation, is a perfect

example of this. When we were developing this illusion, we

couldn’t just walk into an engineering firm and say that we

needed a teleporter. This is a highly specialised, individual

solution that had to be developed from scratch.

Where do you use automation and how do you benefit from

the high level of technical back-up?

Chris Ehrlich:

Obviously we can’t give away the secrets behind

our illusions. However, one technical innovation we can tell you

about is the central roll-up projection screen that we have over the

stage, which is driven using a Festo servo motor. The advantage of

this is that it can be moved to any position. This means that we

have maximum flexibility despite the infrastructure that changes

from venue to venue. The roll-up projection screen is controlled

by our own PLC structure, which operates the Festo controller.

Andreas Ehrlich:

We used to use a turnkey standard solution,

but it wasn’t reliable enough for our requirements. The screen

didn’t move precisely enough to the required position and the

projected image therefore didn’t always fit on the screen. With the

new solution we no longer have this problem. It is taught before

every show and once that’s done we can be sure that it will

operate with one hundred per cent reliability. Automation gives

us security, it relieves the pressure on us and gives us the

freedom to focus on our performance on the stage.

“Automation gives us security,
