Phreak

Oldschool phone phreaking. Back in the early 90's when no kid owned a cellphone, I wrote an ANSI C program that output DTMF tones via terrible 8 bit audio.
Made an even worse recording of it on a mono tape.
Played it back into a payphone handset via my sony walkman's orange headphones.

Voila, free calls! ...

(replicated here in Java for sake of Nostalgia)

Dedicated to Bubbles!
