Virtual Braille Input for Mac?

You know how there is a Braille Keyboard Input for the iPhone and iPad? It's already built in.
Is there anything like that for Mac? Is there a way to type like that on Mac instead of having a External Braille Keyboard/Display?
I know about the Braille Writer App for Mac but I want to be able to type like that all the time, not just in one program.
Thanks
