I finally got this movie (in auction)!
It has been created by artist Jacques Lopez. I bought the only copy left (the artist destroyed the last backup by smashing the hard drive containing the backup, that's part of the artistic process). I thought I should upload it, now that I'm the only owner of the movie.

The artist described the piece as follows:

Night supermarket is ambulation on the shopping center car parks at night, punctuated by the music of Jean-Michel Jarre: "Music for supermarkets".
This album introduced a state of trance, trance applied in driving a car on desert car parks: at night, the freshness, the music, the desert environment, the park becomes a constraint, an event. This thirty minutes video will be sold at a public auction in a single copy: so that this moment remains unique.
Piracy of this work will be encouraged just like the disk of Jean-Michel Jarre was in his time. The master will be destroyed, the vido will disappear from the display. This will be a story to transmit through Peer to Peer.
