(function(){
    document.body.innerHTML += '<pre id="preConsole" style="position: absolute; left: 10px; top:10px; height: 200px; width: 400px; background-color: rgba(0,0,0,.9); *background: #000; color: #fff; z-index: 1000; padding: 10px; overflow: auto; font: 12px/15px Monospace; margin: 0;"></pre>';
    var pre = document.getElementById("preConsole");
    window.console = {
        log: function() {
            var a=[], iCount=arguments.length;
            for (var i=0; i<iCount; i++) { a.push(typeof arguments[i] === "object" ? JSON.stringify(arguments[i]) : arguments[i].toString()); }
            pre.innerHTML += a.join(', ') + '\n';
        }
    };
    window.onerror = function() { window.console.log("ERROR:", arguments); };
}());
