I've created a live time-lapse webcam with my Raspberry Pi Camera.  It takes one photo per minute and has been running since my camera arrived on May 15.  As I'm currently on the road, I've got the camera running in my camper though it's not 100% live -- I'm now only uploading one image per hour when I have my phone's tethering turned on.  Here's a sample of some of the images so far.  Looks like I'm out of time and won't be able to upload the whole grid of hourly images.  To see the whole grid (or most recent live image), visit http://markmarano.com/live-time-lapse-webcam-with-raspberry-pi-camera/ and click the drop down below the image -- choose "grid [since beginning]".
