There’s not much to say about Pavilion Z of the Brno Exhibition Centre except that it looks like a big volume control dial. At this size it will presumably go up to 11.

Fans of GGSS Integrated maps will be pleased to know they now work much better. The betterness includes…

• Automatic zooming to the bounds of a post’s or category’s map points.
• Default satellite mode.
• Logical category ordering in the selection drop down.
• Points from new posts actually show on the map.
• Bacon.

Of course, feedback and feature requests are always welcome.

Near Gladstone in Queensland, Australia is a gigantic, bright-orange lake known as Red Mud Dam. Although the explanations I found were a little confusing, it seems that the colouring is due to residue formed through the process of extracting aluminium from bauxite. I think.

You can see that the colour only seems to be affecting about 2 thirds of the lake, as I believe the mud is processed to remove the residue.

However, I’m sure someone out there will correct me, even if I’m right

Thanks to Stuart Moffatt and Stephen Hope.

Thanks to DDA and Brad.
