2nd Logo (1997) Unexpected Development (1997) Logo: We start out at the outside area with birds flying by in the background. Then the logo (which this time is a "U" with "D" as it's shadow and the stacked words, "UNEXPECTED DEVELOPMENT" underneath), slowly fades in and zooms in while we slowly pan up. Then one of the birds flies in from the right and later gets knocked out by the logo and it stops zooming in. Then the background fades into white.
