Just had an idea for a quick fix regarding the emptiness of the dome on Frihamnstorget, (and a google search shows of course that it has been done a lot ;))
How about sewing and building (…or just buying cheap on blocked) a bunch of hammocks for lying and sitting to hang into the dome? Could be easily removed when space is needed and otherwise provide coziness in the middle.
We could even try out having seats and table hanging swing set up.
But maybe that has already been considered and there are reasons against it or people are not interested or have better ideas. however, though I put this here and see how the feedback is :).
