This was a quickie. Built in one day and with a busload of fun while doing it. I used Yogi's Mars Pathfinder Sojourner which I downscaled 50% to 1/24. Did some tweaking to Yogi's basic design which was already very good but needed some more detail in what I wanted to make of it. The solar panels were replaced with a piece of metallic blue paper which I carefully carved to get some detail back of the individual solar cells. The body was covered in gold chocolate wrapper. The rear instrument box also was covered thus, leaving the JPL logo free.
