Objective: Display a message on a seven-segment display. User will enter the message in an HTML form. Letters will be displayed using an SVG image that displays one character.
Problems: We need to translate from letters and numbers to a set of segments. How do we tell the SVG image which character to display?
Solution: We can provide a dictionary with as few or as many characters as the programmer deems necessary. The programmer can add diagonal or curved elements as desired. The SVG image can take a URL that has a hash that indicates the letter to display. The SVG must have JavaScript that may require a CDATA section on some browsers.
