Psalm 50 Illustrated

I was on the QTC chapel preaching roster this Tuesday, and was asked to preach on a Psalm.  I ended up picking Psalm 50, as it seemed pretty cool on first read.  It's awesome.  Read Paul's Areopagus speech in Acts 17 and tell me that Gamaliel hadn't set him an assignment on Psalm 50 when he was in Pharisee school.  Awesome use of the Old Testament applied to the gospel era.

Anyways, I stewed on it all week, but found it hard to write.  I ended up grabbing some scrap paper the day before and trying to re-write it out with my own indentation to try to 'get' the meaning better.  On attempting to write it out in words, this is what ended up coming out.

I'm not sure what you call it, but my mind was thinking in the style of those videos that have someone illustrating the concepts of a talk while someone's talking over the top.  Kinda like this video.  You know the style I mean?  In my head, I was doing a video like that.

So my question is, did it flow so well because that medium matches the way that I think and so the internal could be expressed on paper very easily?  Or has the way that I think been altered by watching so many videos like that?

Edit: Or is it just a Psalms/poetry thing?
