OK, some of the “disasters” are a bit nitpicking, but there are some truly awful image manipulation efforts out there, some associated with very big companies. Look back over the archives, there are some real classics. Lesson to large companies: don’t penny-pinch, it’s not worth it.
I can’t remember any Autodesk marketing image disasters, although some of you may remember being bemused by the relevance of the the short-lived Subscription Cow. The BENTLEY BIN image is pretty funny, though. Does anybody have any other CAD-related examples?
