Sometimes something strikes us in such a manner that we cannot bring ourselves to drop it... at least not entirely. Way back on February 2 over on the dark side I posted about an error I found, which has since been corrected.
That's not what has been hanging out in my memory bank. What bothered me was that I couldn't find a proper graphic to demonstrate the original error. Well today, quite by accident, my quest ended. This photo is a better image of what was trying to demonstrate.
