Here’s an interesting Kickstarter project.

Urban Air has been designed, engineered, and has secured the billboard to carry the flagship project. With your help, Urban Air will be towering above the Los Angeles freeways in the new year.

The vision doesn’t stop there. Upon a successful launch, it’s our plan and intention to transform the steel and wood of outdoor advertising into the infrastructure of urban sustainability in cities around the globe – actively, publicly, and collectively generating a green global future.
