It only just occurred to me that I was involved in multimedia work years ago, I was in a group that did a light show for rock shows. But we also worked with the St Louis Symphony and the Cleveland Orchestra, lighting pieces by Scriabin and Holst.
We also did four light shows at the Eucharist at my then-parish, Trinity Episcopal. Also for Trinity, I developed a set of slides to accompany the Prayers of the People for a televised Eucharist.
