Hi Debra, Sorry for delay in getting back to you. Has been a while since I had some time in the office. Wow your collection sounds like it has a beautiful array of diverse materials. I am a big fan of petrified wood. The short answer is yes, lots of ideas but with such a broad blank canvas I would not know where to begin. Small, large, outside, inside, on a deck, water on or in front like in the picture. You could break and cut and stack or mosaic like crazy paving. The stone wall in referenced image is just face stone applied to a block wall. I would be happy to have a brainstorm directly with you if you were able to give me some more info. Failing that, go local. Find a quirky landscaper and get their input to assist in designing and building with you. There are so many technical construction aspects to take in to consideration when working with water to ensure the longevity of the creation. I recommend working in with a professional. I hope this helps.
Kind regards,

Benji
