I've been working with some of the people involved in developing this over the summer and it looks like it will be fabulous system- and one that avoids the moral dubiousness of the United Devices Projects (as in , their results are privately owned ).
Apart from climate prediction, some other projects should come online soon, one of which i had a go with the alpha release of, and it had beautiful graphics which represented the calculations being carried out (rather than seeing a graph or just pretty animations).
PS- had lunch with David Anderson and he's a really nice guy as well!
