A kind of physical Facebook [...] - the great colorful wall in the disaster bay, between Rössliwiese and Alpenquai.

In 1995, Cogliatti instructed 55 children to paint the same concrete wall on behalf of the Zuger Schul– und Stadtbauamt (″Zug school and municipal building authorities″).

The wall painting was inaugurated on July 6, 1995, one day after the complete renovation of the Rigiplatz above, which is reminiscent of the same disaster.

With the help of a flat painter and over a period of approximately 140 hours, the artist implemented “her own sculptural and color visions”.

She therefore gave her work the name Trompe-l'œil, which means "eye delusion"; for this, the dominance of the window hatches in the wall had to be broken.
