From the Fallout blog:
"After plowing through more entries than we ever thought possible, we whittled the list of over 17,000 entries down to the 12 finalists and picked a winner for the Fallout 10th Anniversary Contest. The entry that came out on top was 'Grim Reaper's Sprint,' which restores all your action points whenever you kill an opponent. Congratulations to Marc-André Deslongchamps from Montreal for his winning entry. He selected the PC Grand Prize and takes home a boatload of goodies in addition to getting his Perk in Fallout 3. We'll have a little interview up with Marc-André today or tomorrow."
