earthtunnel.com | Added to Ziipa on January 11, 2010
Earthtunnel.com is a virtual project aimed at the creation of a 3D tunnel whose ends meet at the end of a 35,500 km journey (switch to miles if target is American market), the approximate distance of one trip around the world. The tunnel is constructed thanks to images embedded in its walls. Participation in the Earthtunnel.com experience is completely free. It will no longer be possible to participate once the tunnel has competed its 35,500 km journey.
