      A slide deck is the analogue version of a PowerPoint.

      The deck is the rotating ring that you drop your slides into, then project them on the wall with what is essentially just an overhead projector designed to take small vertical slides of film loaded into the deck, instead of just using transparent sheets.

      You’d design all your little film slides, arrange them in order in the deck (think, deck of cards). The deck is what let you automatically swap between slides by pressing the remote to rotate the deck and reveal the next slide to the projector lens.

      I’m 32 but my school was broke as fuck so we were still using overheads and slide decks in 2005.
