Test Your Strength!

Part of the Botanic Lights exhibition at the Royal Botanic Gardens Edinburgh. There is a button in the middle of the trees, and visitors are encouraged to light them up in a test of strength.

We've been every year. And we always end up reminding ourselves of an unarguable truth: trees lit from ground level are kinda cool, and creepy as all hell. On the eve of Hallowe'en, this seems particularly appropriate!
