Raymond Camden wrote a great tutorial on loading style sheets dynamically based on the user’s current weather. He poked fun at himself and the idea a bit at the beginning of his post, but I think it’s honestly a terrifically fun idea. As it’s beginning to get a bit colder as we enter the holiday season, it would be very… cozy… to have a site recognize the weather and respond with some cool blues and whites!
Will I get around to implementing something like this? Probably not. But I find it pretty interesting anyways!
