A while back I had posted a question about creating an overlay using flex slider. I wasn't able to figure that out, but I was able to make it happen using Views Slideshow and Views Slideshow:Cycle. So that I can make it happen again, and just in case you'd like to do the same thing, I have documented the steps here. I've worked through it a couple of times and I believe that I have included all of the steps. If not, please let me know.
