The shadowing of the mound also gives the illusion in the picture of a "face". The "face" on Mars is only a natural landform that was mistaken as something else more than that because of the illusion of a face.      I would argue yes this could be a valueable. The reason this could be valueable is because this can be used anyhwhere in classrooms work offices police office etc. People wouldn't be able to lie about what they done or how they feel inside. This could become a lie test for people who comit crimes.
