Interiors of Atomium, Brussels, Belgium
An exhibition themed reinforced concrete creations was on in one of the spheres. These are used by architects for making façade patterns. Similar patterns are used for aircraft windows too.
There was one sphere full of smaller spheres, thirty of them. Each had a little bed inside; this was the children’s sphere. These were suspended from the upper vault of the sphere; and could be brought up and down giving the effect of falling rain drops. Children can read, write, work, play and wash on the lower floor of the sphere.
Here is a view of staircase through one of the tubes.
