You probably aren't old enough to remember dial-up modems, but, children, there was a time that connecting to the internet was not only slow, but noisy. That noise is ingrained in the mind of everyone who had to endure it, but, thanks to awesome "slowing things down" technology, we can now hear it...700% slower!
What does it sound like?
Mix the soundtrack for Inception with some of the creepiest ambient noise you've ever heard, and it's pretty close. But ,don't take my word for it, listen for yourself! Now!
