An amazing type experiment by Tien-Min Liao. Click for more photos and awesome videos!
“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 my gesture or changed the perspective through which the shape is viewed in orderto transform the upper-case letter to a lower-case of the same letter. Removingor 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.”
