The Space Invader Walk is a pretty inventive way to attract people to the Museum of Contemporary Art in San Diego. For its "Viva la Revolucion" exhibition, the museum has created a giant space invader (that can be seen from high up) by planting 21 space invaders throughout the city as a scavenger hunt.

The space invaders are found on the sides of buildings or on side walks. It must have been quite a challenge for Invader to create a giant space invader in the city, especially when you don't have the birds-eye view for reference.

The Space Invader Walk would be a great weekend activity!
