@TimeGlider :: World War I (source: Wikipedia)
Another timeline app is Timeglider. Timeglider seems to show you few actual timelines, the purpose is more to create your own? Not sure yet why they don't publish more.
I point you here to the World War 1 timeline. As you can see, there's a bit of sensory overload here. Which tends to be the problem with many of these. The authors just can't stop! You'll recall HyperHistory, which is now much improved, yet which long suffered the same problem.
Timeglider says it has 12,000 users. They show 4 timelines. Are you a user? What's yours look like?
