Yo, this shit is pretty dope:
Eternal Sunset endeavours to ensure you can enjoy the sunset live from any location, at any time. As the sunset moves westward, Eternal Sunset continuously tunes into different webcams, chasing the sunset around the globe. This service is currently provided through the use of 206 west-facing webcams across 42 countries.
They need more webcams, though. I’ve been watching the same shot of Tehran for five minutes – that’s four too long.
