How can I make my desk larger/smaller?

The outermost items define the desk's size. Its size adapts dynamically to how much space is needed.

1. To increase the size of your desk, simply grab an item and drag it beyond the edge of your browser window. The desk will automatically grow in size and the scroll bars will adapt accordingly.The desk will automatically adapt.
2. To decrease its size, bring the items closer together (or even delete some of them). Again, the desk will automatically adjust its size.
