Retrographer

This week has been sufficiently chaotic (everyone is sick again) that I find myself without a Friday post. No matter, however--one of my friends let me know yesterday about a site called Retrographer, which is possibly the coolest thing I've ever seen. I highly suggest you check it out, and if you live in a city other than Pittsburgh, please note that the creator of Retrographer is looking to expand his project to other cities.
