It's called MetaClip and it's a tool that lets you store clipboard contents permanently in a portable file format. Development is still just getting underway, but the current version does all the basic stuff it's supposed to do fairly well (stores and restores clipboard contents, lets you organize and filter clips by category, etc.). I've only tested on Windows XP SP2 and Windows 7.
Just be forewarned: it doesn't warn you before deleting stored clips if you select delete from the context menu or if you delete a category.
