Schon etwas älter und vielen sicherlich bereits bekannt. Stealth Light Projector von Frédéric Eyl aus dem Jahr 2005.
Parasite is an independant projection-system that can be attached to subways and other trains with suction pads. Parasite projects ﬁlms inside a tunnel. These tunnels bear something mystic – most people usually have never made a step inside any of those tunnels. Confusing the routine of your train-travelling-journey, your habits and perception the projections parallel worlds – making use of parasite – allow you a glimpse into a diﬀerent world full of surrealist imagery (thegreeneyl.com).
