Ari

What is it?

Ari is a controlling system for animations on a LED wall, specifically developed to manage the LED wall in "Bodegaen" of the student society in Tronheim, Norway.

Hopefully, it may be possible to use the system for similar installations, like the one at the Department of Computer and Information Science at the Norwegian University of Science and Technology.

For more information on Ari, please refer to http://itk.samfundet.no/dok/Ari
