I couldn't resist this purchase from a market in Cape Town earlier this month. It's fab!
Not only does it spin but it will be great for showing all those, as yet, geodetically unenlightened what lines of latitude and longitude are! I'm taking it into work tomorrow.
Later tomorrow I'm off home on the train with my girls. My elder daughter has just discovered a new game (honestly, not my idea) which she calls "grid references". The game apparently involves me giving her a grid reference and her working out the symbol, or me giving her a feature and asking her to give me the GR. She can't wait to play it on the train tomorrow with her OS map. Long live enthusiasm for maps!
