not-paid is an open source repository which reduces the opacity of the website every day until their site completely fades away.
Just load the not-paid.js file in <head> and customize the following variable.
/* change these variables as you wish */
var due_date = new Date('2017-02-27');
var days_deadline = 60;
/* stop changing here */
It's available as a WordPress plugin as well.
Have fun!
