Nowadays there are many tools to digitally visualise your life, your environment and happenings and make it public.
You can put your home-movies on your web-site, or post your camera-phone photos to a online photo-album, or use tools that create maps, satellite or 3d-images to show where you are, or have been.
At the photo-site flickr.com you can see a daily refreshed collection of photos tagged 'burning man', which are posted from the Burning Man festival in the Nevada desert.
The Google Earth tool is used to create a movie of a fly by Seattle tour, combined computer-generated images with live video. With Google maps it is possible to visualise a tour through a city or a marathon course.
