For a device as sophisticated and elegant as neuma, logo, numeral, tech, n, the design should also encapsulate its essence. considering that neuma, logo, numeral, tech, n gives you a "sixth sense, " the design could be a stylized, minimalistic symbol combined with the numeral "6, " perhaps with the 6 subtly wrapping around or interlocking with the symbol. this could symbolize the blend of human and technology, becoming an extension of yourself. the design could employ a sleek, metallic sheen or a gradient to represent its high-tech, ethereal, almost spiritual nature, and perhaps a soft glow or halo effect to emphasize its quality of awakening a 'sixth sense.' as neuma, logo, numeral, tech, n is a fusion of the ancient and the high-tech, ethereal, almost spiritual, you could use a contemporary typeface for the symbol but incorporate some elements to pay homage to its name's roots.
