The Pinscreen Device
A pinscreen is a white screen that consists of thousands and thousands of pins in small holes. Light shines from the side of this platform causing each and every single pin to cast its own shadow. Each pin, being able to slide easily back and forth through the holes, can cast different shadows. The white screen becomes darker the farther the pins are pushed out. The more the pins are pushed in, the lighter the screen becomes, giving a grayish tone and eventually an all white screen again.
Smaller, cheaper models have since been developed as a 5×7 inch toy version called "Pin Art", sometimes sold in Science museums or through the Web and printed catalogs.

Famous quotes containing the word device:
“A bracelet of bright hair about the bone,
Will he not let us alone,
And think that there a loving couple lies
Who thought that this device might be some way
To make their souls, at the last busy day,
Meet at this grave, and make a little stay?”
—John Donne (1572–1631)
