I've had a little fun messing around with Photosynth, a Microsoft research project turned into a Live service. You upload a bunch of photos from around the same area and it makes a 3D panorama out of them. For instance, here's National Geographic's photosynth of the sphinx and pyramids in Egypt. Messing around with this I've made one of half a vase of roses, and a larger photosynth of my office.
As noted previously, my page consists of the aggregation of my various feeds and in working on that code recently it was again brought to my attention that everyone has different ways of representing tag metadata in feeds. I made up a list of how my various feed sources represent tags and list that data here so that it might help others in the future.
