Hi
I came across an interesting illustration in a second-hand book about old musical instruments - a web search turned up a colour version at http://rogerbourland.com/2006/12/20/the-harmony-of-the-birth-of-the-world/ It shows a highly decorated organ case with six stops - and relevant illustrations - representing the 6 days of creation.
Whatever your views on the literal interpretation (or otherwise) of the early chapters of Genesis, it's still of interest.
For what it's worth, I belive that the days of Genesis, whilst they could be 24 hours - after all, God is capable of doing exactly what He wants) are more likely to be longer periods of time during which the various stages of creation happened, called into operation by God each time.
Every Blessing
Tony
