Tien-Min Liao has taken a popular idea (forming letters with configurations of a body or body parts) and executed it so flawlessly and completely that ownership is rightfully hers.
"In this experiment, I drew shapes with ink on one or both of my hands, manipulating my gestures into the corresponding shape to signify an upper-case letter. Then, using the same shape on my hands, I manipulated mygesture or changed the perspective through which the shape is viewed in order to transform the upper-case letter to a lower-case of the same letter. Removing or redrawing the darkened shape on my hands is not allowed in the experiment. The only way to make the model transform from an upper-case to a lower-case (orvice versa) is changing the gestures or the perspectives."
