My thought for this site is that you could use it to generate an interdisciplinary writing task with students. They select a starting location then find its opposite; the writing task is that they narrate the journey from the starting point to its opposite. They could research the different places they pass through and choose their own line of travel (making it either more realistic or fanciful). Integrated activities might include geography (different environments); mathematics (distance and measurement); science/physics (distance & displacement).

Allows the user to generate a URL which will open miultiple user defined links in separate tabs - good for student research assignments and worksheets where you might want to provide a set of resources. Could also be used in presentation handouts.
