I have added the words ANASTHASIA just by doing this. I would create the
letters like this:
111111
11 11
111111
11 11
11 11
and then fill the blanks with zero's (0's), and stick that into BSCR^, which
was previously filled with 0's using fillchar. And instead of zeroing SCR^
each time, you simply copy the contents of BSCR to SCR which is a bit faster I
think. Here's the modified code which is a bit larger due to the dots required
to make ANASTHASIA appear :)...
I have also made it move by itself and allow the user to move it, too. Hope
this helps someone :)... You can modify whatever the letters say at the top
simply by chaning the LETTERS_A variable.... Have fun...This can be put into
SWAG freely..

I have a fairly good voxel-source.
This one is not mine. And I forgot who made it.
