The folks from EA have installed what is probably the world's daintiest billboard in San Francisco's Union Square. At just 14" by 6", the Spore billboard requires a telescope to see.

A handful of bloggers have been abuzz in the past week with news of the latest under-the-radar Burger King promotion. The fast food chain has dispensed agents across major U.S. cities (indications are it’s just been Chicago and Orlando so far) to “lose” wallets.

Yep, the wallets include notes telling the individuals who find them to go ahead and keep the wallets. Time Out Chicago reported on November 12th that Burger King planned to drop 5,000 of these wallets around urban hot spots in Chicago. According to reports from bloggers, the wallets contain actual cash, ranging from a $1 bill to a $100 bill, a gift card to Burger King, a “Drivers License” featuring The King, and a map of Chicago or Orlando area Burger King’s.
