Yeah, vines and shinglers grow all over the crack cork mosaic background. (...) In the cracked cork mosaic, the plants can also root into the sphagnum-filled gaps in the cork.
FWIW, here's another vote for cracked-cork over, well, anything else as a +/- vertical substrate for viners, shinglers, etc. Also, if you use some roundish cork pieces, or I suppose even sections of small-diameter tubes, you can get some proper "dirt" up there and make some trailers & spillers happy. Or you can start your vines in that and let them run rampant elsewhere.
Using different thicknesses of flat cork, and different degrees (<90 up to full 180) of round, you can get quite a bit of "topographical diversity". I like to start thickest & roundest at the substrate level, and go thinner & flatter as I work up. This makes a lot of 3-D animal play space, and helps light punch down further into the viv in any spots without plants. In addition, the thickness of cork dictates the thickness of LFS packing in between. Thinner LFS dries faster, so using thinner cork higher up amplifies the ecological gradient begun with 1) your lights, and 2) gravity draining water downwards, from a relatively hot sunny dry top of viv, to a cool shady moist bottom of viv down at substrate level.
Finally, the cork is dry enough to mount stuff (broms, most orchids) that doesn't want wet/rotten "feet",
even if you keep the LFS packing moist enough to grow a decent moss crop. Really, the versatility and aesthetic appeal of cracked-cork is tops. If you use small cork pieces (more crack, less cork) the cork will just disappear under the jungle. But if you use bigger cork pieces, or just the odd big piece in a field of smaller pieces, you will retain some visible wood for the long haul.
Good luck!
