First, I think Lifepath is beautiful. Being a developer first, and designer second, I often find myself having a hard time breaking out of the mold when it comes to designing my applications. Usability doesn't have to mean boring, and I think Lifepath is a great example of that. I could see a company like Greplin taking this and turning it into an auto-generated timeline curated from the various social networks they can tap into. It's obvious that Dustin out a ton of time, effort, and love into this project, so I hope there is a happy ending!
