Crossrail problems and more picspam.

I went along to see if I could get a better picture of the crossrail railhead - when I got to my usual vantage point I found that although there was a train there, the conveyor belts weren't moving, and there seemed to be a lot of people milling around. And then I realised that there appears to have been a bit of an accident; it looks like the structure carrying the conveyor belt, which has only been working for a couple of weeks, has partially collapsed at the far end:

I haven't been able to confirm that's what happened, but it looks very likely.
Now confirmed - it collapsed on Thursday, there were no casualties.

I also took a picture of a light rail system serving the tunnels; the rails have been in place for ages, but it's the first time I've noticed a vehicle using them:

Finally, here's another family of swans on the canal; this time the young are a little smaller that the adults

Back in the dawn of time I had a simple Windows CE GPS program for an ipaq that gave you various bits of data such as coordinates, altitude, what satellites were used to get the data. etc. It WASN'T a moving map or satnav program, and it was pretty tiny, well under a meg. It wss VERY good for showing students how GPS works.

Can anyone point me at anything like this for Linux? Or for Mac? Needs to support a Bluetooth GPS receiver.
