It's not impossible at all. It just has 3 sides, is concave, and you're looking up at it. The tricky thing is the lack of perspective. It would only look like this with a very long lens.
It's half a cube (well, the outer walls of one), it's just rotating the opposite way you first think it is. Not impossible at all, just a fun few moments of confusion until you catch on.
That is correct. It is only impossible to build this IRL. Thanks for explaining how this was made. That is really interesting. 🙂👍

But it's like one of these guys:
Edit 2: Keep your eyes only on the dark grey side.
I have actually built this dragon, thanks for the hit of nostalgia. 😊
Edit: It is probably inspired by the optical illusion you posted, but made actually impossible.
It is... Very much possible to build? What are you missing? It's just 2 vertical gray walls and a white roof.

Light gray side moves through dark grey and vice versa. Rotate the dragon 360 degrees IRL and you will see why this isn't possible.
Edit: even if you made the sides at a perfect opaqueness, there is no way it would look like this IRL.
You're seeing a cube from above rotating left. That way doesn't work. If you instead see a cube from underneath rotating right it very much does work.
