The world is made up of two kinds of people: those sadistic monsters who leave the key-board clicks turned on on their iPhones, and the sane angels who keep that shit off.

If you put yourself in category #1, boy, do I have a product for you! Noisy Typer is a free, open-source software for OS X, developed by Theo Watson, of the Free Art and Technology lab (F.AT.).

Built on openFrameworks version 0071, Noisy Typer runs in the background and will replicate the click clack sound of an oldtimey typewriter, while you compose your emails and pen your memoirs on your word processing program of choice.

Noisy Typer has a distinct sound for letter keys, the spacebar, backspace, return, scroll up, and scroll down—so if you're jonesing for a little Mad Men action, you can just power up Pages (or Word, or whatever), hit the keys, close your eyes—pour some Scotch?—and make believe you're sitting right in there in the center of Sterling, Cooper, Draper, Price.

...Otherwise, I'm not sure why you'd want to submit yourself to this kind of *cruel cacophony? [TheVerge via fffff]

*If you do, though, please be kind and keep your headphones plugged in at all times. Because you are probably the only terrible human on Earth who actually wants to hear this.
