I've enjoyed watching the "arc" of GraphSketcher. I went to college with the original developer, who, upon being sufficiently annoyed with having to draw supply and demand curves by hand in Econ 101, wrote the code that eventually became OmniGraphSketcher. Classic itch-scratching if I've ever seen it.
Robin later managed to turn the program into his master's thesis, a conference paper that won "Best Paper" (http://dl.acm.org/citation.cfm?id=1518870), and an acquisition by the Omni Group, where he went on to develop the iPad version.
He later left Omni, which is part of the reason that they decided to discontinue and (later) open-source the product.
I'm look forward to seeing what people do with this code -- as well as what Robin might have up his sleeve next.
