BlocksCAD takes a different route and uses an interface similar to MIT's Scratch which makes it easy for kids or adults with no prior CAD experience to start designing. The end product will be released under an open source license and will run from within a browser, making it easy for anyone to start designing (a standalone desktop app is a stretch goal).
