So apparently that flash game from a few months ago was just the game version of this commercial. You know when Letterman drops stuff off the roof? This is the same concept on steroids. Replace 'Letterman' with '~50 cameras' and replace 'watermelons' with '250,000 superballs.' And instead of dropping it off the roof they drop them off San Fransisco. I believe that it is a few years old, and it was on TV for a while, but this link leads to a gratuitous extended online version. This other movie of a paint apocalypse isn't so bad either.
