Algebraic Transformation Tool, Extended(repost)

I am designing an educational interface for teaching algebra rules. I am looking for a programmer to extend an existing graphical system which allows users to interact with physically displayed equations in meaningful ways. A graphical system written in Java already parses mathematical expressions and displays them on the screen. Two interfaces support equation transformation. For more details on the original system, see the spec for the original task (algebra transformation [login to view URL]). The task of the coder will be to extend these systems in the following ways: 1) Create an interface to allow the user to set the font and font size of the graphical interface 2) Extend the transposition scheme to single elements 3) Extend the graphical interface to infer transformations from the location of the mouse release. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform Windows XP and OS X
