Free Culture Achievement
The idea of this achievement is to embrace the wonders of Open Source (and all the other similar licenses like GPL etc) in our geohashing ways. To complete this achievement, one must use a item (or items) of Open Source (or similar) equipment (i.e. software or hardware) to reach a hashpoint. The item needs to actually be used on the journey (e.g. you can't count your desktop computer, the item must reach the point itself).
Examples might include such items as a PDA/handheld running such software, or even something like a GP2X (or similar handheld) to view saved images of the map. Or you could carry around a laptop, but those things get heavy after the first couple of kilometres/miles :) Bonus points if you do this dressed like a ninja.
Apart from the usual, a picture of the device and its use of Open Source is sufficient proof.
