How about these as UI designs? Click for a bigger image. I'm no UI design guru (and I was advised not to do art for GSCE…), so please complain loudly if you don't agree or have better suggestions. When we've got a simple GUI fleshed out we can work towards user interactions and how to use an API. Thanks.
