For the record, I'd like to say that it's not messagebox... It is remarkably cool, and it would keep users entertained for a while (in my office, hours...)
I wonder if this would go over better than the progress bar for the logon script... My domain admins didn't like the kixgui progress bar, because they said users might think something was installing... 
Like the Please wait while your logon script runs wasn't specific enough...
