Thanks MrChile and Tom.
The planning of this image was extremely complicated:
1. Screw with it until I liked the result.
2. Then stop.
Come to think of it, isn't that what Picasso did with all those plates he painted?

Thanks Kenny, Greg and Robert.
Look at it upside-down, Greg, and your eyes will uncross . But if your balance isn't very good, you can flip the pic upside down instead .
