jBreadCrumb was created by Jason Roy of CompareNetworks Inc. It is a jquery extension for breadcrumbs which allows long names to be used within breadcrumbs, and can adjust the amount of visible text to ensure that the current/first node are visible. It also has the ability to mouse over truncated breadcrumbs and show their entire text.

For examples (more information) see: http://www.comparenetworks.com/developers/jqueryplugins/jbreadcrumb.html

Since version 0.2.2 jBreadCrumb now supports jquery-ui themes.
