that's very cool looking.
I was just about to express skepticism about this claim:
Blank Keys to Type up to 100% Faster
Like on a piano, since there are no keys to look at when typing, your brain will quickly adapt and memorize the key positions. Within a few short weeks users increase their typing accuracy and find themselves typing up to 100% faster.
I first read it as saying that the lack of printing would help you type faster since your brain wouldnt be distracted by the printing on keys, and i was going to point out that that contradicts most of what we know about the brain.
but on second reading i think they are saying that the lack of lettering will force you to become a touch typer, which will in the long run lead to faster typing, which seems reasonable enough. pretty interesting idea actually.
