I was messing around with EarthCam’s Top 25 Webcams of 2005 and came across the webcam set up by Riverbanks Zoo on their Koala enclosure. I was very impressed at the quality of the image (looks great on full screen) and the technology used, where the koala movements are tracked so that if it moves off screen, the camera pans to follow the action. Check it out
Addendum: The webcam is moved from one animal to another every now and again, so you might not get a koala, but you’ll surely see one of their fascinating animals.
