Intriguing storytelling, thank you for this. As a bit of a subway-fetishist, I quite liked riding the low-res train.(trivia note -- my Mac download didn't run until I chmod+x'd the executable in the package...)
I'm totally aware of the Mac issues, sorry! Been away at events the last couple weeks, and with me not having a Mac it's hard to really work out if fixes work, but thanks for letting me know.
