Sorry for not getting back to you already. Nearly all the code we use is our own proprietary Open GL (http://www.opengl.org/ ) based App written by ITO that combines the key elements from the transport modeling world and film special effects to allow us to understand, manipulate, render and analyse very large transport systems. We designed this to combine a semantic understanding of the transport system together with fast rendering. For this animation we used 52 weekly planet dumps and then rendered the individual lightning flashes in each week from the relevant planet dump. Each frame had all the planet data available to it and one of the tricks was to knock back the processing time to something were we could render 2000+ frames in a sensible amount of time. I have a background in real-time transport management and modeling and my colleague Hal Bertram has a background in film special effects. You can read more about Hal's earlier film work here (http://www.halbertram.com/about.html ) including some details of when we worked together in the late 1980's at the Henson Creature Shop and his more recent work on Harry Potter and on Troy. There is more detail about his techniques for high-speed rendering available (http://www.halbertram.com/trick/index.html) which I don't pretend to understand but his work at Henson in the 1990's was all about creating the ability for CGI characters to be rendered in real time so that the real actors and the crew could see what was proposed at the time the film was created rather than weeks later in post- production - and this of course had to happen on computers that was far slower than today's ones. We have put in a good couple of years building up the code-base so that we can now do things like this relatively easily and we hope to do lots of new fun stuff with it in 2009. One of the things are wanting to do is make it possible for OSM Mapper users to create their own animations and large visuals through our website. We are working on speeding up the rendering processes to make this possible at the moment. It is our intention to continue to support OSM contributors with free on-line products (such as OSM Mapper) and also to provide paid-for subscriptions for individuals and smaller organisations as well as for professional users for other map and transport based products to keep the show on the road. We expect to offer subscribers to OSM Mapper the ability to create shorter animations for free, with larger ones available for 'pro' accounts, available for a modest annual fee, Pro accounts will be for people who want to burn more computer time and bandwidth creating larger animations or many of them. We are still figuring out the details, but I think you can be confident that it will be attractive, universal and affordable.
