As I mentioned in another place trying to merge the ideas of Ravenmore and Wojciech didn't work out. I fully understand the reasons and again have to thank Wojciech for his incredible submission. Nonetheless Ravenmore now will continue to work on the final layout. He's got a number of great ideas and I am pretty excited about how all this will work out. Here's another preliminary design study, showing off the direction to which things are moving. Comments are welcome and Chris (Ravenmore) is also curious about feedback.
