Lightning Rod is a cross-platform Dropbox client for flash drives. It was written in 30 hours at the AngelHack hackathon in Boston, MA in March 2012, where it placed as a finalist.

It is written in Java and takes advantage of SWING for the GUI, Dropbox's Java SDK for accessing files, and FileMonitor.java for monitoring the file system for changes.
Wait, so does this actually work?
Mostly. The team has not continued development since the hackathon, so the code and interface are very much unpolished. There are definitely bugs. There are also several quirks the team would have liked to have made better. For example, files remaining on the flash drive after a previous Lightning Rod session are not recognized. The files of interest must be re-synched for each new Lightning Rod session.
How do I use it?
You'll need to compile the program into a JAR file. We used Eclipse and Netbeans for the development, but it's been a while since we've compiled it. We'll try to write a guide on how to get started building Lightning Rod soon.
Is there any hope of you finishing it?
There is always hope. We're posting the code as-is with no warranty (see LICENSE file) in case anyone wants to contribute, but otherwise we do not have plans to finish it in the immediate future.
