Incredible, interactive and ecological technology which allows to build large, monochromatic signs which are making a lot of noise while changing – they capture viewer’s attention. Electromagnetic way of control together with mechanical inertia of display links creates an effect of content appearing out of chaos of shaking pixels. Watch the video.



This is a device where art, electronics and precise mechanics meet

Technically speaking such a sign is a set of moving plastic disks with permanent magnet, which are driven by magnetic field. This technology was widely used for public transport or in sport signs where disks were slow and static. We managed to elaborate control method which allows to show moving pictures at a rate of 15 frames per second. Thanks to this we can show videos, animations and other effects.

Key features

  • The signs can work outdoor, programming is done by a pen-drive with a program constructed from still images in BMP format and AVI animations. Other programming methods are also possible.
  • Images are constructed from moving disks turned colored side to observers The disks reflect light. The more light the better but never more then at ambient.
  • It catches attention with movement and differentiation and not blinding light which does have to fight the Sun.
  • Energy is needed only to change content what results in a very small power consumption.

In our world dominated by LEDs, it creates a difference.

New York Yankees Stadium

Yankees Stadium from New York has chosen Alfa-Zeta as a supplier of this technology to realize a large sign – part of exhibition committed to Yogi Berra at a the New York Yankees Stadium in New York. The sign is a part of a mural showing this famous player. It is showing a presentation including various statements (“yogisms”) from which Mr Berra is well known.
