Like I said, it's pretty early on and more or less in the alpha stages. A marginal update has been pushed out and you can access it through the same link. It's mainly small bug fixes. Look for a larger update over the weekend.
There is plenty more to come including customized icons. The reason the home screen is blank is that a customized screen is in the works using the composer. It's been taking a little longer than expected though. The idea will be to have a more interactive home screen.
We've put out beta v0.1.03 which includes screen transitions and a sliding app drawer which should alleviate the issues of the busy background and no home screen icons. You can download it at the previous link. We're still working on the whitespace issue on the landscape home screen.
