I’ve been having way too much fun with these. Last week I made an interactive sharable NYC subway map called “What’s Your Subway Station Number” and it’s been making its way around the web, being covered by Gothamist, Curbed, Brooklyn Magazine, 6sqft, and more.

And yesterday I made one for Boston, which you can see here.

Boston.com just did a nice writeup, and I’m hoping it brings Bostonians as much fun (and lost workplace productivity) as it’s brought New Yorkers.

Based on the stats, people have spent a combined 370,000 hours playing with just the NYC map alone. Crazy!
