I'm heading to Sydney today for SMX (see my last post for context). This past Saturday night ago was Earth Hour, an event which I understand started in Sydney where people around the world are voluntarily encouraged to turn off lights for one hour in recognition of climate change. It is of course only symbolic, not a real fix, which bothers some folks but it is OK with me.
Anyway, the Boston Big Picture, one of my favorite blogs which I've talked about before, had a post showing before and after photos of various landmarks during the earth-hour blackout. It is quite stunning - click on each photo to see it fade in and out of darkness. Highly recommended for taking a look at. Above are a few of their photos from the Sydney Opera house which I will be seeing for the first time in person very soon.
