 Each face appears on the sculpture for a total of 5 minutes using various parts of individual 80 @-@ second videos . A 40 @-@ second section is played at one @-@ third speed forward and backward , running for a total of 4 minutes . Then , there is a subsequent segment , where the mouth is puckering , that is stretched to 15 seconds . This is followed by a section , in which the water appears to spout from the open mouth , that is stretched to last for 30 seconds . Finally , there is a smile after the completion of the water spouting from the mouth , that is slowed to extend for 15 seconds . Of the original 1 @,@ <unk> subjects filmed , 960 videos were determined to be usable for the project . Originally , the set of images was presumed to be the beginning of a work in progress , but as of 2009 no additional videos are planned .
