Game vision

So, me and Love-lei are doing our hidden objects game with famos landmarks. The game will have 8 locations home, the five landmarks were you go and find a clue for the next location, and the two fake locations made to throw you off, and of course, the last one which is a suprise. You travel finding scrolls that have two equations which give you the longitude and latitude co ordinateds. (Hint: look at the outside of the scrolls before you pick one! In some locations there are 2, a real one and a fake one.)
