Follow-Up:
If you are interested in the Easter Island boards, let's talk. I went to the American Museum of Natural History in NY and photographed one of the stone copies of one of the wooden boards. The "pictographs" on the strange boards came into focus when photographed from an angle. When the negatiives of the photographs are overlaped they will match and form a colored picture. I need someone to help me do research. I believe the people who made the boards used equipment that is not in existence today. Don't answer this if you are just curious. I'm looking for someone who is serious and has the time and money to devote to finging out if the patterns on the boards relate to solar energy used by people in the past. To do this requires making a 4 inch high glass or plexiglass model of a viewer that will "read" the boards.
