Ultra-light private jet concept

This was a design concept I poked around at one afternoon several years ago. Didn't really have a clear objective in mind, I just was playing around with the concept of a very small ultra-light private jet. Single seat and not much in the way of cargo space. By current military standards it would not be really fast, but it would be the hot ship at the local general aviation airfield. Like some classic sport cars. Not the fastest things on the road, but a blast to drive.
