DFTBA

Dont Forget To Be Awesome!

I used BF to try my hand at a code golf puzzle;
http://codegolf.stackexchange.com/questions/10532/write-ascii-art-obfuscated-code-read-as-and-resulting-in-dftba

Challenge:

The challenge is to write the most elaborate code, embedded in ASCII art that reads and prints "DFTBA". For example, the following reads DFTBA:

oooooooooo.   oooooooooooo ooooooooooooo oooooooooo.        .o.       
`888'   `Y8b  `888'     `8 8'   888   `8 `888'   `Y8b      .888.      
 888      888  888              888       888     888     .8"888.     
 888      888  888oooo8         888       888oooo888'    .8' `888.    
 888      888  888    "         888       888    `88b   .88ooo8888.   
 888     d88'  888              888       888    .88P  .8'     `888.  
o888bood8P'   o888o            o888o     o888bood8P'  o88o     o8888o 

And the following, in bash prints DFTBA

echo "DFTBA"
The challenge is to write one that does both.

Winning conditions

Valid answers, (all conditions at my discretion)

Can be clearly read as DFTBA
Print DFTBA when executed
Must be functional with no Internet connection
have letters of equal height
must not have more than 80 columns
must not have more than 10 rows
Points (highest sum wins)

Rows * Columns / 32
Readability: 25 for legible, 50 for very clear
1 point for each different non-whitespace character used

My Submission

Start by roughly writing DFTBA in ASCII (this doesn't fill the max limit of 80 columns by 10 rows so I have some 'play' room):

A very basic BF program can write the required 5 letters in order to the screen. This is by no means the best BF program, but I wrote it in 60 seconds as that wasn't the difficult part in this challenge:

+++++ +++++
[
    > +++++ ++
    > +++++ +++
    << -
]
> -- .
++ .
> ++++ .
< ---- .
- .

Here it is again with some notes about ASCII values:

// D : 68
// F : 70
// T : 84
// B : 66
// A : 65

+++++ +++++
[
    > +++++ ++     // F : 70
    > +++++ +++    // P : 80
    << -
]
> -- .             // D : 68
++ .               // F : 70
> ++++ .           // T : 84
< ---- .           // B : 66
- .                // A : 65

Now we can remove my comments and squash that code into one line of commands, and embed it into the ASCII art I drew before. I have alternated between AT symbols (@) and BF commands (the squashed line of code I have embedded throughout is at the end):

Now I need to bulk this out with more @ symbols to get as close to 80x10 as I can without using gratuitous spacing (I achieved 80x10):

[email protected][email protected][email protected]@@@@         @[email protected][email protected][email protected][email protected]@@     @@@[email protected][email protected][email protected]@@    @@[@>@[email protected]@           @@[email protected]

Now I must mingle in all the ASCII characters between 32 and 127 for more points, excluding ASCII value 127 which is DELETE and the 8 BF commands:

[ ] , . < > + -
Which means: 127 standard ASCII characters -32 (0 to 31 are "non-printable"), 127 which is delete and these 8, leaves 87 characters for me to embed. This gives the following result:

Note that in the above, I have replaced the last @ with a comma ','. This is the BF command to wait for user input, so my program will run and print DFTBA as required by the rules but then hang indefinably waiting for user input or the user to stop the program. There is nothing in the rules about what the program should do after printing DFTBA. This allows for the maximum possible points using only the standard ASCII characters from 32 to 126.

At a later date the op confirmed that extended ASCII characters can be used. I can include the characters from 128 up to ASCII decimal value 255. Now my answer looks like this:

A row through the output above is not quite lined up with the rest of the output (roughly the middle row). This picture shows that its just this site not displaying it properly. Notepad will display it correct where as Wordpad wont. Fixed width font issue I guess.

Writing this in Windows XP (in 2013?!) causes problems because none of the built in fonts seem to have all the extended ASCII characters. The only way to prove all extended ASCII characters are included is with a Hex editor/viewer. This is from Notepad++ with the "HEX-Editor" plugin:
