Piccolo

We used a really great UI toolkit call Piccolo to handle our Idea Pages display. This is an open-source technology that came out the Human Computer Interaction Lab at the University of Maryland, and the godfather of Piccolo is Ben Bederson although the project has since expanded to include a wide range of users and contributors.

Piccolo comes in two flavors: Java and .NET. We naturally used the Java version! Most applications that use Piccolo are of an academic or research flavor; we are one of the few commerical products.

The zooming and panning features of Kerika's Idea Pages, plus the miniature views found in the sidebar (use View-->Pages to see the sidebar) are a direct benefit of using Piccolo.

Piccolo's a great toolkit if you want to build a great UI!
