An ordinary computer mouse was used to make the alien healing device.
The title makes reference to "The Promised Land" that describes the land promised by God in the Bible to the Israelites to Abraham. The promise was fulfilled when the Israelites completed their forty year journey following the Exodus from Eqypt led by the prophet Moses.
