No, Gwyn: it doesn't overcome Hare's need to have more than four numbers. Nor does it persude people to look at the board at times other than the four-hymn sandwich slots, so that they realise that they do have the words to the Latin in their hymnbook.
No, what you need is a cute projector: like this one.
given that the ones that people have seen are from German-speaking sources, perhaps you need to Google "Liedanzeigen" maybe coupled with "Projektor" or "Leuchttafel"...
One further thought: rather than spend the money on an electronic board, why not contact your local (Cathoilc) secondary school DT department and get them to make a wooden one with enough slots for your needs? This has the potential to be the basis of a GCSE woodwork project, helping both the student and the Church. Similarly, if you needed an electronic solution, I am sure that could be devised by a school. Either project could be a positive link between parish and school, a link which is all to often lacking, in my experience.
Think I'll stick with me services sheets: item begins, everyone looks at sheet and sings. You have the verses you want and are not limited to items from one collection.
Hymnboard = item begins and everyone shuffles through hundreds of pages finding the right place.
Me next plan is to steal/burn/hide the people's Mass books. All the way through the readings you can hear people flicking pages and saying to the bod next to them: "What page is it?" And Lord know why they need them when there's a reader doing what readers do – reading!
I know what you are saying Nick but I have to say that since our church brought in Mass books people seem to be paying more attention.
Some readers obviously do not go over the reading before Mass, some rush through as if they don't want to be there, others read sooooo slowly ..... with ..... very ..... long .... pauses .... so .... you .... lose ... the ... zzzzzzzzzz.
I am looking forward to Summer School and Peter Tibke's workshop.
Back on topic - I agree that Powerpoint or projectors can draw the eye away from what is the altar.
