We don't know whether we should stand back and applaud the logo of South African analytics company Eighty 20 for its ingenious nature, or just shake our heads at how meaningless the logo would be to someone who didn't know what it was supposed to represent. This one is strictly for those of you who are extremely computer literate!
If you interpreted the blue squares in the logo as 1s, and the grey squares as zeroes, they would give you two binary patterns - 1010000, and 0010100. You can probably work out where this is going now - that's how the numbers '80' and '20' are written in binary code. It's incredibly niche, but then we suppose you'd want this kind of attention to detail if you were seeking to employ an analytics company, so perhaps it helps them attract customers. At least you could be sure that they're technically-minded!
