Simple. The thing that you touch when using the internet is your keyboard. So here it is.
ouch. I totally don't like it. It looks like some crazy african braille thing. (sorry)
but. your idea is good. why dont you use one or two keys, maybe the D and I, or both in one. I haven't see anybody working with the keyboard. so you have potential here!!
don't be pissed, I'm honest but I wanna help.
you are right. it is ugly. i don't know what was in my head. anyway i'm tierd of it to change it and i don't know how to delete the entire idea.
but don't give up. don't delete it! the idea has potential, maybe search for some keys close up on google and redraw them, give them a nice look and you got it. =)
