The steel truss curves into an icosahedron, but the blue parts make no sense (there are vertices with 3 edges on it), so it isn't a polychoron, rather a disconnected figure. You might be looking into an icosahedral pyramidal subdivision of the truncated 600-cell (tex).
Yes, indeed, nowadays there are lots of playgrounds with polyhedral trusses and some spanned in ropes for kids to climb therin. I even remember that at my childhood there have been playgrounds with trusses of stacked cubes, mostly in pyramidal arrangement.
