I've written about my life stream before, but sofar they are always textual. Lifeblob takes the life stream to a whole new level, it makes it graphical and puts the events on a social time line. It allows you to visualize your (and that of others) on the web. It nicely picks up your tags and this allows for interesting intersections of information.
Not too many services are supported, making it less useful. However the nice embedding feature makes it still worth the have a look. If the embedding doesn't work, check it out here!
If you are interested to give it a try, let me know so I can send you an invite.
