Perhaps you are thinking of Daniel Rozin's "Wooden Mirror" (1999)?

That's a very good one, but in my case it was a huge billboard that was advertising movies and stuff.
It had cubes in different colors so from further away it would look like an image.
Rozin was a direct influence on me! Seeing his stuff ~10 years ago got me thinking about unorthodox displays.
