I have a shed and a camera so I combined the two.
Shedcam looks at my backgarden so that those abroad can see what the weather is like in Essex in the UK. It also allows me to see my kids having fun during the summer months, to see the rabbit running around the garden or to ensure nobody has stolen my shed. Very hand.
It runs using an MSI Starcam 370i and a bit of software called DORGEM . I had previously used Easywebcam but that got a bit flaky at times and their support site has links to some other cameras which I didn't want to be associated with.
