This design is a pathfinder which has a proximity sensor and a camera to record the path of travel. The inner box has a microprocessor and a internal storage which detects the pulses from the camera and stores it in the internal memory. This satisfies the Accessibility parameter card since proximity sensors are easily accessible. The larger case has been shelled out thus satisfying the modifier card. The Future parameter card has been ignored to satisfy the blind gameplay card. Thus this design satisfies each and every conditions. Challenge card #1 "Pathfinder!" — Create a 3D map that captures your path to work or school, but the object must be small enough to fit in your pocket. Parameter card #1 Future Parameter card #2 Accessibility Modifier card #1 Shell — Hollow out a part of your design. Gameplay card #1 Blind eye — Ignore one of your chosen parameters.
