Can somebody explain the use of pinhole cameras and twin lens cameras?

I want a Holga camera, and on the website there are stereo cameras, pinhole cameras, and twin lens cameras. I have no clue what these mean.

1. The only available twin lens reflex camera - and all those commonly found second-hand - takes 120 film. They are basically two cameras, one on top of each other. The upper camera simply forms a viewing image, its lens is coupled to the lower lens of the taking camera to allow both to be focussed together. The most famous camera of this type, the Rollei , remains in production; there is a normal Rolleiflex model with a standard 80mm lens and a wide-angle model with a 50mm lens, both giving 6x6 cm images. It seems unlikely that a digital version of this camera type will be made, other than as a novelty item - a miniature 2Mp version of the Rolleiflex has already sold well in Japan. Pinhole cameras are usually homemade, though some can be bought commercially and feature useful holders for roll or sheet film. Although you cannot buy a digital pinhole camera, you can easily adapt interchangeable lens SLRs by using a pinhole incorporated into a body cap. Although simple and generally limited to very small apertures, pinhole images have some unique characteristics that can make them interesting and occasionally useful.
