I think the concrete layout might only work on similar wide screens (say, width > 3 x height or something). I have a vague idea about a 3 column layout with the slideshow in the middle, but haven't thought much about it.
However if I can make the slideshow work in a good way (I think I like the google search idea best, as it would require nothing more to use - maybe with an override option, so if you have a certain folder you'll get the images there instead) that might be generally applicable. So, if you already have considerations (I saw some requests) for different layout options it might become a part of that. It doesn't sound too difficult to make the layout selectable, but I don't know the concrete architecture and possibilities etc.
The search might find silly images from time to time, but I think the slideshow would look really cool so still worth it ;-) It also might be possible to select "I don't want to see this image again".
