Double vertical resolution

Nice project! You could double the available vertical resolution by using ASCII "half-blocks" with fore- and background colors, like:

Hi, thank you for the advice, maybe before aomenting the vertical resolution I'd better improve the efficiency of the algorithms, otherwise it would be too slow.

I will add this improvement in the TODO
