From a distance, the Duillusion® titled 'Where are you now?'
changes to 'You are here' when you stand close to it.

At the Threshold Festival in Liverpool, UK, these two identical Duillusions®
were displayed on opposite gallery walls as an interactive illusion.
Viewers stood by one and then went to stand by the opposite one
to experience the effect.

Is the bike part of the installation? We'll never know.
