Pen zooming

Speaking of working with small screens:

Researchers from Microsoft Research, Microsoft Research Asia, and Tsinghua
University in China have devised an interface that goes a step further by
allowing a user to zoom in on relevant content and collapse irrelevant
content with a single pen stroke. The interface could eventually be included
as an extension to small-screen Web browsers.
