Here's a page that displays your Meta stats and can track differences.

It uses localStorage to keep a record between browser sessions and highlights any changed values. For example this user just got an upvote on that raised a question's score from 7 to 8:

The page also takes URL parameters, EG:

http://jsbin.com/ximuhuzo/1?poll=no&interval=77&sitename=meta.stackoverflow&userid=2963652

Please note:

• Currently, the saved baseline is updated every time data is fetched.
  So, if polling is enabled, the change highlighting will only appear for one poll interval.
  This will be the next thing I change if I make any enhancements to this page/app.
• The Last "Active" date-time values are currently raw Unix time from the API. I'll format them in the next release.
• For now, current totals are shown rather than delta values.
