Follow the Trail to Freedom in the 1850's. History Now.
Yes! I've only traveled 3 steps on this interactive march, and I'm hooked to find out what will happen to my character. So far, as a runaway slave, I'm farther south than I started, so curiosity and anxiousness are rising.
But let's talk a little about open source. This is just the type of wonderful applet that has so many possibilities...audio narration, animation, dynamic map, a ticking clock,... Way to many possibilities to sit there, statically, with no hope of further development!
Open sourcing this would turn it over to a nation of students who might just adopt it and make it something huge.
Excuse me, I have a slave to get to freedom.
