The first one is still in its beta form, but I created an account so that I could explore its potential for transformational use of technology in my classroom. Tripline, sounds like what it is. It allows you to use Google Earth to map your trip as a timeline of events.
It also has inset maps and narrative facts. There are rewind, fast forward, restart, and pause controls for students to manipulate as they move through the animation. The military battles range historically from Civil War to World War II. I may invest the $20 tax-deductible donation to receive a CD of all of the animations that are on History Animated. It comes with additional teacher resources and materials not found on the website.
