When i was in kopenhagen, i wanted to make a picture of the mermaid, but it was so crowded with japanese people that i put my hassy upside down above my head to get rid of the crowd...

What i want to say is that there are a lot of tools that can be put onto the body to use it in a different way. No electronics involved, so no real problems that can not be solved in the future.
Expensive? I don't thing to. It was expensive, until the digital age came up. Without this i probably could not have bought a hassy...
