Here's a vision of the Wrocław Orbital Ring (WRO-O):
What does it look like?
-Imagine a giant, shiny doughnut with a hole placed vertically on the ground – perhaps near the irrigation fields in Osobowice or in place of the side halls of a train station. The structure: A large, white-and-silver circle that, from a distance, looks like a portal to another dimension. The facade: Instead of traditional windows, the entire building is covered with intelligent panels.
During the day, they reflect the Wrocław sky, and at night, they glow a pulsating, neon blue.

Center: Inside the doughnut's "hole," there's nothing – it's an empty space where, thanks to magnetic fields, a small test space shuttle floats and docks.

What's going on there? (Zones in the Center) This is no ordinary office.
The building is divided into four arcs: Southern (Training) Arc: A large g-force centrifuge and a zero-gravity simulation pool. Instead of chlorinated water, astronauts float in a special gel, gazing at the Sky Tower panorama.
Eastern Arch (Scientific): Here, Wrocław students and scientists grow space-age potatoes and test rovers destined for Mars.

Western Arch (Mission Control): A room with a giant, curved screen. From here, a crew in "Wrocław Space Agency" sweatshirts controls flights to the Moon. Northern Arch (For People): A café at the very top of the hoop. You sip an espresso at 80 meters, and the floor slowly rotates, offering a view of all of Lower Silesia.

Why the "O" shape? The circular shape is no accident.
Firstly, it perfectly complements Wrocław's rotundas (like the one at the Racławice Panorama). Secondly, hidden inside the structure is a circular particle accelerator – a large, magnetic tube that generates artificial gravity on the lowest floors.
