LAG Magic. First appearance at Paris La Défense. 97 keys of impressiveness.

Looks like they've salvaged some parts from Destination Docklands' ruined Grand Central aka Immeuble.
As for the Mad Max controllers: There were some more remote keyboards made by LAG for Jarre, such as a completely gray, "double-necked" bigger successor for the Circular, and a very strange one, being mostly straight, but having the upper few keys bent up. They may or may not be the Mad Max models.
