Epidiascope

The Epidiascope is the wizarding equivalent of a projector, but with the added features of being able to hold numerous waxing recounts from omniculars as well as making them three-dimensional, so the viewer can see all details much better of the recount.

Description
Originally used to broadcast Quidditch matches for viewers that could not attend, the Epidiascope is also used heavily by schools with correspondence courses to allow distance learners to see lectures better and allowing them to see certain breakdowns of formulas and other such educational devises. They are also used in skrens for entertainment purposes.

Epidiascopes come in a variety of forms, but they are all very sturdy and made of a type of metal.

History
Devised in the 17th century, the Epidiascope is largely ignored for its other handheld component, the Omniculars. Though not as useful on the Quidditch Pitch, the Epidiascope has been long beloved by those who cannot often watch matches in person as well as students who cannot attend lectures from afar.
