We talk much of timelines and this was presented to me as a timeline app; it's byline is "Time Captured". A quick exploration shows it to be more of a narrated presentation engine. Much of the content reminds one of TV: much self congratulation and omphaloskepsis.
Yet consider Paul Revere's Ride, a reading of Longfellow's The Midnight Ride.... Every student should have heard this poem professionally read, and what a way to do it, with beautiful pictures and maps of the era all available for exploration.
There's a History section, to help get away from the more personal uses. Yu still get James Bond Movie Posters, Helmut Newton, and 2009 Dodge Challenger. Still, 75 Years of the Popemobile perhaps has potential to draw in a young man interested in cars to some connection with the 2000 year old papacy?
Black Death quickly shows learners a map of the plague's spread; the dead, the dead rats, and a contemporary sketch of the ill, with the body parts appropriately censored as the age demanded.
Capsules can be a platform for students to roll their own, and sports a few good themes. Meta-app for showcasing the richer content, anyone?
