For the grout nest, I cut up a dollar store plastic plant and glued pieces of it onto it, again for visual interest. I also had a glow-in-the-dark figurine (tree spirit / kodama from princess mononoke) that I added in there too, it might look neat at night.

You can see the acrylic is slightly scratched from the grout removal process, that's normal. You can fix it with a heat source if you're carefully (too much and it burns), but I don't really care enough to do so.
