Go tiny or go home. That's the Spore marketing philosophy apparently, as 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.
Fortunately, EA has installed said telescope and aimed it directly at the wee Spore advertisement, giving passersby a chance to enjoy some smartly conceived marketing. If you happen to be in the Bay Area, specifically Union Square, you have a brief opportunity to check it out. Everyone else can live vicariously through pics after the jump.
