No disrespect but I would not call this "clean". The design is overwhelmingly cluttered and distracting. Especially given that each symbol is obscured by a black square with an arrow covering it. The symbols are themselves very small.

Maybe get rid of all the noise and just display the symbols in a nice grid without all the fluff or layers.

It feels really noisy and specifically, not clean for me too, so much that it pushes me away. It's interesting and fortunate that it works for the author and some (most?) commentators.

I agree. Unicode references sites are numerous and yet this is one of the worst I’ve used in terms of distracting visual noise.
