Faster than you can say "infinite cat," our intrepid code artists have entered their final lap as the competition is extended by a whopping half an hour!  Yes, you heard me right, folks: with the sun now set, the mysterious Team 4 now appearing from the ether with a database design to beat the band, and Team 1 leaping into a tenuous grasp of the lead with their online book tracking application, the thrust-and-parry of this seemingly endless day and night of madness continues!  Oh, the insanity!
