Based on my read through this thread I updated my shop items so none of the primary images is a circuit board... Sure they look great to me and I know exactly what they do, but I'm probably in the minority with that opinion. What I've got there now looks a lot less cluttered and should be simpler for the casual viewer to comprehend.
