moonGARDEN is a set of 22 big round things that glow, in Discovery Green in the heart of downtown. Some of the moons play music, others put on shadow puppet displays now and again. It was quite lovely, walking around them in the dark, but also rather strange.
The whole thing is sponsored by Ikea which I imagine means that, after the ten days of the exhibit, they're all being deflated and flat-packed, ready for reassembly the next time 22 moons are called for.

You could wave a torch around in front of some and they'd interact with you!
