Brad Neuberg and his team have announced Hyperscope 1.1.

The HyperScope is a high-performance thought processor that enables you to navigate, view, and link to documents in sophisticated ways. Neuberg (pictured) made the announcement in his blog. It’s the brainchild of Doug Engelbart, the inventor of hypertext and the mouse, and is the first step towards his larger vision for an Open Hyperdocument System.

The HyperScope is written in JavaScript using the Dojo toolkit and works in Firefox (recommended) and Internet Explorer. It uses OPML as its base file format. It is open source and available under the GPL.

What’s new in 1.1
The 1.1 release had three primary goals:
1. Get a high-quality HTML transformer up on the network, especially for working with the W3C’s documents
2. Bring HyperScope architectural document up to date
3. Fix some small bugs
For a bit of fun, the team has put up a Paper Airplane research paper/project.
