Mad genius Moroccan carpet weavers

I sometimes look at this website 1stdibs.com for inspiration. A lot of antique dealers from all over the world put their stuff on there. I like to look at the lights and the carpets mostly. The other day I found these 'Vintage mid-century Moroccan carpets'. I haven't seen any Moroccan carpets like this before. Were the carpet weavers trying to make the craziest looking carpets ever, or was it just by accident?
