Themes in the JS objects and a question about creating/connecting Maxobjects

Does anybody have any idea how to change the theme / color schemes in the js/mxj objects?

I can't seem to find a way to do this...

Is there a sub-folder somewhere in the main Max folder where I can drag in new themes?

Also, I wonder if anybody can tell me why this function isn't working properly for me.

I'm not well versed in Javascript, so it's probably something obvious I can't figure out.

here's my code:

function bang() {
    // Define the "this.patcher" preface
    var patch = this.patcher

    // Define left / right locations for new objects
    var left=300;
    var right=300;

    // Define variables for the Groove~ and Sig~ objects
    var groove_obj = patch.newdefault(left, right+30, "groove~");
    var sig_obj = patch.newdefault(left, right, "sig~");

    // Creates the Groove~ and Sig~ objects
    patch.create(groove_obj);
    patch.create(sig_obj);

    // Connects the Sig~ object to the Groove~ object
    patch.connect(sig_obj, 0, groove_obj, 0);
}

The two objects are successfully created and placed, but don't seem to be patched.

Thanks!!
