Our minister is adept at using PowerPoint for his sermons, using it properly I mean...almost never are there words, but images that are congruent with the words he speaks.
A while back he did use words. As he spoke, the screen spelt out an acrostic, there were phrases after the letters, but I don't recall them:
I was pronouncing it in my mind as it formed:
[getting nowhere, what could this be?]
[ah, some Greek word that he'll explain for extra impact]
[oh, maybe a Hebrew word, could be interesting]
[hmm, no, maybe Greek...pronouncing it with my dim memory of Koine]
[oh...tog ether (short 'e' sound rhymes with 'ever')]
It dawned on me latter.
