Finally, I have added enough information to the page to make it interesting. Here it is: Amy's Round The World Trip Maps
Behind the scenes, there is a Python script that reads an input text file containing place names and locations, each leg of the trip including mode of transportation, and boundary coordinates for the small maps on the right. The map data (land and water) comes from xearth. To find the location of some of the more obscure place names, I look them up in the GEOnet Names Server from the National Geospatial-Intelligence Agency. I drew the little transportation icons myself, after failing to find an appropriate set online. The page is laid out with CSS, and since I don't really know all the good CSS layout tricks, things tend to bunch together and overlap if your browser window is too narrow. And the small maps use the same (rectangular) projection as the main map, which makes them look squashed, especially higher latitude locations like the UK (it should be taller - Edinburgh to Swansea should look nearly twice as far as Swansea to London).
Yes, sometimes I do this sort of thing just to play with technology.
