According to the website Fritzing.Org:
Fritzing is an open-source initiative to support designers, artists, researchers and hobbyists to take the step from physical prototyping to actual product. We are creating this software in the spirit of Processing and Arduino, developing a tool that allows users to document their Arduino and other electronic-based prototypes, and to create a PCBlayout for manufacturing.
Despite the wacky name, this looks like very cool software. Just avoid using the phrase, “I’m fritzing around with this circuit.” Someone’s going to have to develop a module for Manhattan-style layout, though.
