For all you armchair navigators out there that follow the Volvo Ocean Race there's a new update to the Virtual Spectator software thats worth downloading. It seems to have a fixed a number of bugs and now even shows isobars correctly on my laptop. There's also a resume option so you can see whats happened since last time you ran VS.
And of course it still makes lovely pictures like the attached, which Tillerman should like!
