Legal Walking address the fact of becoming an illegal alien and therefore tries to create "legal space" within US borders. For that purpose a device will be designed for "attaching" Argentinean embassy ground (or any other country) to any type of shoe and thus be always walking, standing and touching Argentinean ground.
The project functions more as a gesture than as a real solution to the problem since embassy ground is defined by perimeter. The other more serious problem is that if illegal aliens such as myself use this devices they will be easily identified by the authorities and therefore the hole purpose of the project will be reverted. This could be fixed by designing the device with a "Stealth" approach (unlike this sketch).
