Password, password time is here!

Once again they are threatening us with every 120-day password changes. If this had been the policy when I started, I'd have burned through 30 passwords by now! As it is, I think I'm on my... 3rd one? I'm not fond of it, so I won't mind (if it really comes to pass), but remembering a *new* password every 4 months will not be fun. The other down side is that when you think of something clever, you can't exactly share it.

...though perhaps I tend more towards geek-tastic than clever. I've been working in chemical symbols and mathmatical expressions when I can, but still only have a few that really fit the bill.

Ideas, suggestions, tips? I'm still looking for a way to us a 'W' for Tungsten, but can't really find a way to work that into a password...
