>On the other hand, in one of our apps, the splash screen is the login screen. The logo is in the upper left hand part of the screen, there is some text at the bottom, but mainly it's the login form. That way, if one feels it's absolutely necessary to animate the logo, at least it won't interfere with the user's ability to just get on with the job.

That's fine. What I don't like, and find annoying is animation and/or blinking. It gets tiresome fast.
That's the gist of this thread.
