* Print your own logo in developer tools!
* Step 1: Convert your logo to ASCII text here: (I used color output)
* Note: Is possible that you'll have to resize your photo in order to retain aspect ratio
* Step 2: Remove the <pre></pre> tag that is surrounding the generated code, replace with "[" and "]"
* Step 3: Run the following regexes (*DON'T ALTER THE ORDER*) in order to convert to JSON (Works in PHPStorm and Sublime Text 2):
* 3a: Find: '<\/span>' (without quotes)
* Replace: '<\/span>\n'
* 3b: Find: '<span style=\"(.*?)\"[^>]*>(.*?)<\/span>' (without quotes)
* Replace: '{ \"text\": \"$2\", \"style\": \"$1\ background-color: #FFF\"},'
* 3c: Find: '<span style=\"(.*?)\"[^>]*>(.*?)\n<\/span>\n' (without quotes)
* Replace: '{ \"text\": \"$2\\n\", \"style\": \"$1\ background-color: #FFF\"},' //(Note the escaped backslash)
* 3d: Replace last comma before closing \
* Note: background-color is used in firefox (background in console is light-gray)
* Step 4: Save your JSON file
* Voila!

* hardcoding parameters in JS file.
//Params that will be passed to console.log function
var params = [];
//String that will contain all the logo characters

//Request to our JSON file
var request = new XMLHttpRequest ();
request.overrideMimeType ("application/json"); ('GET', '', true); //Replace with URL to your JSON file
//Executed when request was made
request.onreadystatechange = function onJSONFileRead () {
//If request is sucessful
if (request.readyState == 4 && request.status == "200") {
//Parsing JSON file
var json = JSON.parse (request.responseText);
//Adding JSON entries to params array
for (var i = 0; i < json.length; i++) {
message += '%c' + json [i].text;
params.push (json [i].style);
//Adding string to first position of array
params.unshift (message);
//Using apply to pass params as array
console.log.apply (console, params);
//Some other nice things
