I wanted to put waterfalls in a terrarium for a while now, but I wasn't able to make it happen in previous renditions. I also had other things to work on. Nothing beats a standard junglestyle terrarium, but I think this is a really cool concept that's awesome to watch. That said, you really need to see it in person to appreciate the view. The waterfalls are fairly substantial, but the video can only translate it so well.
Enjoy the build and let me know what you think about it in the comments!
