Cabral, a copywriter and art director, helped Fallon to take the title of YoungGun Agency of the Year, beating last year's winner, Crispin Porter + Bogusky.
The 85-second "balls" spot, which first aired on UK TV in October, is set to the acoustic track 'Heartbeats' by Jose Gonzales and features multi-coloured balls that cascade in slow-motion down a San Francisco street.
The spot was described as a "brilliant idea" and "brilliantly executed" by award officials at the ceremony in Sydney, Australia.
Its Argentinian creator, who is based in London, wins the $5,000 prize purse as well as receiving an invitation from the YoungGuns organisers to sit on the 2006 YoungGuns Jury.
Andy Fackrell, co-executive creative director of 180 Amsterdam and 2005 YoungGuns jury chairman, said: "The Sony spot will no doubt pick up a few gongs over the next 12 months -- it was nice that the jury here in Sydney got to see it first. It was less effective over shorter lengths but got full value in its longest format: a great choice of music, director and editor, it reached its maximum potential due to its craft."
The Sony ad was created to launch Sony's Bravia LCD television range. It was directed by Nicolai Fugslig and edited by Russell Icke. Media agency was OMD Europe and OMD UK.
Saatchi & Saatchi Worldwide picked up the YoungGuns Network of the Year award for the second time after its win in 2003, with wins from its offices in Australia, New Zealand, South Africa, Brazol, Argentina, Norway, Malaysia, the US and Singapore.
YoungGuns is the only international advertising award in the world for creatives and students under the age of 30. It was created in 2000 and was the also the first international award that offered cash prizes for the winners.
