A touch screen rolls up by body heat

动画说明：

A touch screen rolls up by body heat, and when cooled again. Image: Germany, late 19th century, rectangular, orange-brown, probably colored printed gelatin (in earlier times such images from the swim bladder of the fish Hausen were produced), rolls up on the palm or the breathing on by the body heat, golden print.
