Very clever set of styles and transitions. A little tricky to match the images with the transitions to get the right effect, but when you do, it's very effective!
Concentric Circles is very good, and a piece of fun!10 out of 10!
I make a slide show maybe 3 to 4 times a year. I haven't used the transitions yet.
Going in circles.
Great way ro highlight almost any slide. Needless to say always a polished professional way to create a slideshow.
