We recently took a trip to Boston. Until we get an actual post up about it, here's some fun visual goodness for you to play with:
You can see more on the photosynth website.
I also used Smugmug's Camera Awesome iPhone app a bit on the trip; it lumps all of the photos into one gallery which I dislike, but at the same time, it does so automatically so they're all available for you to behold right this very moment! (And because the iPhone geotags the photos it takes, you can even see where they were taken.)
