If you’re lucky enough to be in Vienna on the 8th of October, be sure to check out the glowing plant-like solar trees that will line the streets near the MAK museum. Designed by Welsh designer Ross Lovegrove, the Solar Trees bring a sense of optimism to grey urban environments and remind us of a greener future.

Excellent idea!
