Buenas a todos!
He encontrado esta página, muy curiosa, y si le das a F11 en el mozilla o Opera es más realista :D:D:D
http://hackertyper.net/
Es una página que simula una de esas consolas que escriben los hackers de las pelis a velocidad ultrasónica (estaríamos hablando de unos 1200km/h :eek:) en verde y negro.
Examinando la web he encontrado el archivo script.js, en el directorio raíz de la web. Ese es el script que hace que funcione todo.
Funciona de la siguiente forma:
Hay una carpeta (hackertyper.net/files/) que contiene archivos de texto plano, que tienen escrito códigos de programacion en C, y cosas así que parecen "chungas". Al dar a una tecla, se escriben 3 carácteres (depende de la velocidad que le pongas, yo le puse 10 y va fumao xD).
Probadlo, está bastante bien.
Un saludo.
jajajajaj buenísimo! muy gracioso!
Hey le encontre un bug o no sé que será, clickea varias veces:
"DB Error, overload!!!! Crap, system crashed :/"
