For snooping, of course. You think you can silently hop fences and climb fire escapes chasing after that cheating wife of yours with a huge D-SLR swinging around your neck? No, but it'd probably be a bit easier with this diminutive camera in your pocket instead.
The tiny device measures a little over 6sqcm and weighs just 14g. It uses automatic focus so you've only got one button — for the shutter — to worry about when you're perched on a ledge outside a third-storey window. In addition to taking 2MP 1600x1200 stills, it also records AVI video at 30 fps at 640x480 resolution to the included 2GB microSD — though it does accept cards up to 32GB. But you'd better be quick with your spying, the battery only lasts 30 minutes on a one-hour charge. It's available from Hammacher Schlemmer for $US100. [HS via Geek Sugar]
