The Grrranimals standard worked. People would match up symbols to see what worked together. Why cannot technology do the same? Yes, the cables plug together, but one has a turtle icon and one has a car icon?
I am genuinely curious to read more about this, but a google search for Grrranimals doesn't give me anything to work with. Can you provide a bit more info, please?
(if this was a joke, consider this my admission of egg on my face)
It's "Garamimals". It's a clothing line for very young kids where they can match the tag on a shirt with a tag on the pants and have an outfit that "goes together."
