Yesterday I got one of those miniature digital cameras, a tiny little thing made from brittle plastic that looks like it’ll last for about a fortnight before it disintegrates.

It has no proper memory, so if you take the battery out (or if it goes flat) all pictures in it will be wiped. But the quality is just about acceptable and it will fill the need I’ve often felt for an easy way of capturing fleeting moments that would otherwise escape forever.

So here’s a couple of pix taken while roaming Liverpool Street station in search of a sandwich this lunchtime, and one of the descent into the bowels of the earth on the Waterloo and City Line at Bank.
