WHERE does the BLACK INTELLECT manifest itself?

So I look at an object as simple as a piano and see a manifestation of the white intellect. I see the concept of standardized musical notes based on their frequency. I see the transcription of complex music into a written language. I see the idea that a musical instrument of such intricacy successfully be conceive of and constructed. I see the engineering and craftsmanship of transforming raw lumber and steel into a complex and functional instrument and then I see that instrument being mastered by human beings to create beautiful music. The piano is but a single example and, mind you, it was created as an instrument of leisure and entertainment, not even of survival. It is just one of millions upon millions of objects, systems, protocols, etc. we see every day that manifest the culmination of white intellect over the past several thousand years. Where can I find such an object that manifests the culmination of black intellect? Not something built on the foundation of the white intellect but is of uniquely black concept, design and construct. Show me this thing. I want to see it.
