Description
"LinkerLogs are a new system of interlocking plywood building pieces for kids based on a design from the 1950's, this time digitally-fabricated on a Shopbot CNC tool. They are modular so that additional pieces can be created that will fit any existing pieces, and the system is licensed under the Creative Commons license so that anyone can use the design or add pieces, with the only addition that they share any modifications that they make. Since they're a modern variation of the popular Lincoln Logs toy that many of us grew up with, some people call them "Obama Logs" or "Obama Boards"!
LinkerLogs are licensed under a Creative Commons Attribution-Share Alike 3.0 United States License, and as long as you stick with the standardized spacing and size of the notches and plank widths, you can add any kinds of pieces that you want...hooks or shelves to make a wall system out of them, architectural details like arches or flying buttresses to make building models, or just some interesting pieces to make it a more versatile toy system. In addition to the Creative Commons License we also require is that you make the files for your new pieces available so that others can add them to their sets, even if you are selling them. If you're not willing to do this please don't base your designs on LinkerLogs!" (http://www.linkerlogs.com/)
