I like the idea a lot. Especially the embedding of note-name in the note itself as an additional measure to the spacial line-distance, as I'm not terribly great at dealing with interpreting the spacial gaps (especially when the note is more than 3 or so lines away). But I find the symbols confusing in their own way, and not because of the language barrier others have mentioned (they're just a mnemonic, the words cease to matter after a certain point and other mnemonics can probably be devised for other languages). I find them confusing because I think there should be a progression to them. And the progression of A and B I find doubly confusing, because in music the notes go up, but in this the darkened part goes down. I look at a B and intuitively think it's an A and vice-versa. I think I'd prefer a system where they look like clock hands, more or less. A is 10:30, B is 1:30, C is 4:30, D is 7:30, E is a slash going through 10:30 and 4:30, and F is a slash going through 1:30 and 7:30. I think I'd find that more intuitive. (note: all diagonal so they don't conflict with the spacial lines)
