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:
“Syntax is the study of the principles and processes by which sentences are constructed in particular languages. Syntactic investigation of a given language has as its goal the construction of a grammar that can be viewed as a device of some sort for producing the sentences of the language under analysis.”
—Noam Chomsky (b. 1928)
