When I spend Christmas with my parents in Pennsylvania, we usually spend Christmas Eve looking for the best, over-the-top-lights-will-give-you-radiation-burns home lighting display in my parents' neighborhood. We fondly refer to it as our "merriment tour". I'm spending the holidays in San Francisco this year, and conducted a world-wide merriment hunt via YouTube. This display claims to have a low carbon footprint because the lights blink only in sections at preset times. Frankly, I don't see how on Earth this display could possibly have a low carbon footprint, but I suppose I'm glad they tried to consider it when creating this masterpiece. Be prepared, this will blow your mind.
