Making these videos is fabulous fun! 26 years ago in London, I was working with The Hedges-Wright Group ~ a multi-media design agency doing almost exactly this sort of thing. Banks of carousel projectors, as many as 16 deep at times, all quietly firing away behind sound-proof glass ~ lovely effects, transitions of graphics, photos and words, with great copy writing and rocking sound systems.
And now, all this while later, one can resurface those skills and make such a production on a laptop! Very excited about the visual digital marketing world at the mo. Makes a nice change TBH from design for print.
Cheers & best regards, James.
