Sqworl is an online bookmarking tool that saves a screen capture of each page you bookmark. To help you organize your bookmarks, you can create multiple groups of bookmarks in your Sqworl account. Should you choose to share your bookmarks you can share one or all of your bookmarks groups via the unique urls Sqworl assigns to each group. You can add bookmarks to your Sqworl account by manually inputting urls, using browser bookmarklets, or via iPhone app.
See Sqworl in action in the video below.

Applications for Education
Sqworl could be useful for sharing a collection of links that your students might need to complete a lesson. If students are using Sqworl, the visual aspect of Sqworl provides a helpful reminder of why a site was bookmarked and what that site is about.
