Travel through an equation: RFID visually tracks where people go

Here's some OpenSource (freely developed and available)  RFID software  that shows where people go in a conference.
It seems like it could be used to create math solutions (dots or lines). As players solve the math puzzles, or follow street maps, their pathway should show up as a math solution.  For instance, you could have someone travel the beltway around a city to create a circle.
