The ALP Alain Colmerauer Prize is supposed to become a yearly award for Prolog applications. I too missed the call though. I got a mail that says it is still possible to submit. It is a self-nomination where you must explain your application in 3 pages. See The ALP Alain Colmerauer Prize – Association for Logic Programming for details.
If you need a couple of days, it might be wise to contact the organizers beforehand to make sure they can still accept the nomination.
