Can someone help me with these blocks?

[tqu3]

Hello, I've been looking for an idea to build my storage. I found this one: https://imgur.com/gallery/xjpcy
My question is: what kind of walls and blocks did he use? I marked these I am asking for (attachments).
And the second question is: how did he make these 'two-ways' waterfalls? I also marked these on my screenshots.
Thanks for help!

Screenshot 1: The hands might be smooth marble blocks.

Screenshot 2: The top part of the waterfall is a painted Boreal Wood Table. The waterfall itself might be waterfall walls but the colour is wrong. The waterfall blocks may have been painted cyan. Or mods might be in use.

Screenshot 3: By hammering a block into a half-block, the water will flow over the block and create the waterfall effect you see. That's how the waterfalls in the screenshots are made. To get the water to flow through the blocks, the blocks are actuated.

All screenshots: To make the water colour cyan, a fountain (Ice in screenshot 2) is in use. Waterfalls can be coloured with gemspark blocks, but there are no cyan gemspark blocks.
