I've successfully installed the Force.com IDE on my Mac, but now I can't figure out how to launch it!

I've looked in Applications and found both a Pulse and a salesforce.com folder.  The Pulse folder just has a copy of the installer and an uninstaller; salesforce.com has a Force.com IDE folder with an uninstaller.

If I launch the installer, there's an option to launch the IDE, but I'd like to just launch the IDE directly.

Where is it hiding?  After launching, I found "~/Library/salesforce.com/Force.com IDE.app" in my process list.  Is it OK to launch that directly?
