In 1999, Camille Utterback and Romy Achituv created Text Rain.

It is "an interactive installation in which participants use the familiar instrument of their bodies, to do what seems magical—to lift and play with falling letters that do not really exist." [1]

Participants can "stand or move in front of a large projection screen where they see a mirrored video projection of themselves in black and white, combined with a colour animation of falling text."[2]
