I refer to my calendar a lot during the day, but I don't always have my calendar program running. Most of the time I just want to glance at something to confirm the time/date of an upcoming event, or just double check a date: "What is the last Sunday in May? Oh right, the 30th."
It occurred to me today that I could make life a little easier if I could have my calendar embedded in my Desktop. Those of you who remember Microsoft Windows' "Active Desktop" feature may shudder in fear at the idea because, at least in my experience, Active Desktop was a complete and utter disaster. It never worked well, if you could get it to work at all.
There are extremely geeky ways of doing this but MacOSXHints.com had a simple solution I didn't even know was possible: Fluid.app. Now I've used Fluid.app for a long time, but I never knew what the "Embedded SSB" or "MenuExtra SSB" actually did. Turns out that either of them are a potential solution, not just for calendars, but for any web page.
[Editor's Note: Fluid just recently went open source, and though the blog hasn't been updated yet, we're told the SSB creator is now open source as well.]
