Howdy peoples of CSS-TRICKS.. I am not new to coding but i am very new to plugin authoring (yeah i know im way behind the curve). But im dabbling with a few lines of code and seeing about turning it into a plugin. Ive read the documentation from the jQuery source, but im having trouble with settings and using the settings as parameters.

Here is the code i am wanting to convert:

function r_num() {
    return (Math.floor(Math.random() * 256));
}

!function seizure() {
    $('body').css('background', 'rgba('+r_num()+','+r_num()+','+r_num()+',1)');
    $('body').html($('body').css("background-color"));
    setTimeout(seizure, 50);
}();

The jsFiddle has my code that i am using in attempts to convert to a plugin (fail). If y'all have some suggestions or hints, i would be very grateful. I can read tutorials all day but until i actually sit down and do this stuff, i wont understand it. And i think this is a great little starting point for me.
