In this work called ‘The writing is on the wall (not Belshazzar), a distance sensor detects the presence of anyone within half a meter of the work. If someone is detected, a focused blue light appears on the wall in front of it. The light moves around the wall forming letters, which, in turn, form words. It spells out ‘I LOVE YOU’ three times to give the viewer a better chance of being able to read it. It pauses a short time and if it sees someone is there it repeats the message three more times.
