Bubbling Trains ~ Accessibility Fireworks ~ Roads of America ~ Gulf of Finland
Helsinki-based GIS enthusiast Topi Tjukanov makes lovely visualizations of e.g. road and traffic data.

The Gulf of Finland really shows the shipping lanes to an extent I hadn't previously understood.

Lovely, I love the bubbling trains and am now frantically seeing if there is SOME data I can use to steal this concept

A lot of cities provide transit data in GTFS. Not real-time but it will have the latitude/longitude of each stop and their scheduled times.

Love this guy. I stumbled across him in the last couple of weeks too via the Roads of America image. As it turns out all his interests align with mine.
As he says in the text he got the idea from the Roads to Rome project.
Which in turn gave me an idea:
All Roads Roam to Leeds (png)
(Done with PostGIS, pgrouting with a combination of the OS Open Roads and OS CodePoint datasets, The set off points are the point locations of inward postcode areas - M1, SW1, NE12, etc - snapped to the nearest road)
For a while now I've had this idea to animate my local bus timetables as an "if I can do this then I've proven to myself I understand" project. Bus timetable data has bus stop to bus stop data but there's nothing about the route on the road. I have to substitute my own instead. Then I have to break up the roads so that graph vertices exist at bus stops as well as road junctions.
A way to go yet, but now I have pathfinding in place it feels like that heavy lifting is done.
(fwiw, search about for TransXchange and NAPTAN if people are interested in relevant data sets. TransXchange have the relevant UK timetables and NAPTAN is bus stops, train stations, etc and their locations)
