The photograph is taken looking up in a room. There are thousands of cables hanging down from the ceiling to the floor, with LEDs attached at regular intervals. The room has mirrors on the walls, on the ceiling and on the floor, so in whatever direction you look you see this. The whole this is programmed to shown different colors changing over time, combined with music and sounds. You can go through the room through a predefined path where the cables are shorter and don't reach the floor, allowing you to walk under them. It gives the illusion that you're in the middle of some infinite arrangement of lights, going on in all directions, sometimes moving, sometimes rotating, or just pulsating with the music. The room is part of a wider art installation called "teamLab SuperNature", in Macau, and it is quite a unique experience.

Thanks

I'm not so sure. They forgot the citations, and also the acknowledgments for the project that gave the funding.

Norfolk Island Pine

Thanks

Hmm, I guess I should have squeezed it – no idea.

Thanks! It's a pet peeve of mine when people use an abbreviated genus name without having written the full genus name first.

I'm afraid I don't (even though I'm old)

It tasted pretty much like a yellow kiwifruit, nice and sweet and better to me than the green ones. I was disappointed however that it was still mostly green inside.

That's it, Aquaria KLCC in Kuala Lumpur

I guess that (1) there are enough other roots in the ground, and (2) the root in the air may be able to extract humidity the air, and also water directly when it rains. Not sure what species this is but in some trees roots also have the function to help with stability, like extra stems.

You can eat the seeds, right?

I don't know

Can't confirm what grows in front of that cathedral, but probably not, because those irises grow along lakes and rivers. (Insert comment about how many lakes and rivers in Brussels have been asphalted over making the city's emblematic flower a rare sight.)
