The underlying map is modern across all timelines. What would be super awesome is if the underlying map would also change, based on historical propery deeds, maps and ariel photos. For example, the 1893 world's fair is when much housing was constructed. The entire coastline also changed during this timeline. This would be an order of magnitude more work...
I'm curious -- each section (after the transitional animation) seems like it translates quite well to being a fixed page, and I'm wondering if you've looked at there being an easy way to generate a version that could be printed?
The reason I ask is that I'm working on a family history project which involves various locations, maps, newspaper stories and old photographs, and whilst something interactive feels like it would be an engaging way to do it, for the long term it's always good to have a printed copy of anything :)
I could imagine if there was an easy way to generate a print version of your articles, some people would pay for a copy (that was printed professionally in a suitable photobook-style format).
Apologies if there is a simple way to generate this and I've missed it in my cursory glance around the code :)
