Pin Art or Pinscreen is an executive toy patented by Ward Fleming. It consists of a boxed surface made of a crowded array of pins that are free to slide in and out independently in a screen to create a three-dimensional relief. Other similar product names are "PinPressions" and "Pinhead". Pinscreens were previously applied as animation in films.
Pinscreen toys were once made of metal pins. Because the metal pins were heavier and bent easily, newer Pinscreen toys are generally made of plastic pins.
A giant 4' x 8' pinscreen is at Technorama in Winterthur, Switzerland. This screen is like a large 3D drawing pad that can work with different sizes of paintbrushes for calligraphy.
