The camera obscura (Latin; "camera" is a "vaulted chamber/room" + "obscura" means "dark"= "darkened chamber/room") is an optical device that projects an image of its surroundings on a screen. It is used in drawing and for entertainment, and was one of the inventions that led to photography. The device consists of a box or room with a hole in one side. Light from an external scene passes through the hole and strikes a surface inside where it is reproduced, upside-down, but with color and perspective preserved. The image can be projected onto paper, and can then be traced to produce a highly accurate representation. The first camera obscura was later built by an Iraqi scientist named Abu Ali Al-Hasan Ibn al-Haytham, born in Basra (965-1039 AD), known in the West as Alhacen or Alhazen, who carried out practical experiments on optics in his Book of Optics
So, basically a box with holes that will project images on the walls inside the box. They attached the large box to the back of a golf cart (shown below) and drove people around campus as they sat inside. Here are a few pictures from our journey!

The short video shows images being projected on the wall inside the box while we drove around campus. So, while the image is upside down, you can see how clear the colors and images are. It was pretty cool!!
