Artist Jay Shells is handy with a street sign, and he’s fused that skill with his love of hip-hop for his most recent project ‘Rap Quotes’. The signs pair rap lyrics shouting out iconic locations in NYC, at the location mentioned. Rappers like Nas, Mos Def, RZA and GZA get signs, and there is plenty more, for whatever side of Manhattan or Brooklyn you’ve heard about. Surely there’s an app idea here somewhere.
