That nut cracker in the picture is a spin off of a senior design project I did for cracking a wide range of hazelnut sizes without sorting.  Mark Shepard presented my senior design project to DTACP and got $5000 to build it, and John Beshaw built what is pictured there.  Last i heard Mark was trying to patent it and sell to Turkish hazelnut farmers. 
The lesson I learned is if you have an invention and don't want others trying to make a buck on it, put it under some general public domain.

Mark my apologies i should have not jumped to conclusions, it looked alot like the one I actually was involved in http://www.forestag.com/processing.html the terminator on the far right
And no I claim no property whatsoever to the design, its not unique and I would gladly share.  I was just commenting on this as I know people who have tried to make money on it, as you can see their is even a patent pending on it.
My only point was that it would have been a good thing to put a public domain license on ideas intended for open source like this so people don't try to patent later.  Please relax and refrain from saying how full of fecal matter I am.

As far as I am concerned there is not one machine element that is a new innovation that  is eligible to patt.Every part of my rendition of a nutcracker has been around for 4-5 hundred years.The components are updated everything else is old hat
