Cities I’ve Visited is one such app that I like. You can add new cities either by scrolling, zooming & clicking, or by typing in a name. I like maps so I find it pretty interesting to see where I’ve been.

The application itself uses the Google Maps API so it’s interactive. Unfortunately the embedded version of this app for blogs is just a static image. You can’t change the zoom level or centre point, which is annoying, since you can see I’ve never been to America or Asia.

One day I might have a go at building my own app for fun. It shouldn’t be horrifically difficult to build a simple, single-user app for having an interactive map with points on it. The difficult parts are making it multi-user, and having a system for adding cities by name (rather than by grid reference).

I could even steal the work of my colleague, who built a map of wireless hotspots at Bristol University.

Pedestrians are probably the most dangerous element of my daily commute through central Bristol. They may be lighter than cars, but they stop more suddenly and change direction more unpredictably.

On a regular basis, pedestrians who have looked directly at me still fail to see me, and walk into the road anyway. As often as not, these people are using mobile phones or iPods.

I could go on forever about unobservant or careless people, but I won’t. Today.
