Make blog has published "The Open source gift guide". It includes Open source hardware, software, project and more for the holidays.
It is a nice idea and list of open source gifts for geeks.
There are hundreds of gift guides this holiday season filled with junk you can buy - but a lot of time you actually don't own it, you can't improve upon it, you can't share it or make it better, you certainly can't post the plans, schematics and source code either. We want to change that, we've put together our picks of interesting open source hardware projects, open source software, services and things that have the Maker-spirit of open source. Some are kits, some are open software projects that you'll need to build hardware for before gifting, and some are just support for the projects/groups that do open source. Included in this guide are things you can get from the MAKE store too (we try and have as many open source goods as possible).
