I'm bored at work and thinking back to my middle school days when I got my start in entertainment technology. Sometime in 1999, when I was in the 7th grade, a touring group came through the theatre with a presentation titled "The Big Picture Show". It was an old-school multimedia presentation promoting anti-drug and anti-peer pressure ideas. It involved at least three fast-fold screens, at least 6 carousel slide projectors, dissolve/sync unit, a 16mm film projector and a Tascam 4-track open reel tape deck. I came in early that morning to help the group set up. I remember helping align the double-stacked slide projectors and assisting with the sync of the entire show. The presentation lasted about 45 minutes and involved at least 4 tray changes and two reel changes. I don't know why this came to mind today but thinking back I kind of wish this type of system was still used (it probably still is but digital projection has caused this style of show to fade away). Does anyone else have interesting stories about extreme multi-media syncing/hectic tray changes/design of a show like this?
