This is a DEMO to switch a *NIX terminal from text to _graphics_ mode on the fly.
The graphics characters are limited to lowercase 'a' through 'z' and this DEMO just prints a small subset to see what a fun, kids level, 8 channel Logic-Analyser/Digital-Oscilloscope might look like.
This may not work in every *NIX style terminal but does work on default terminals using bash on OSX 10.7.5, PCLinuxOS 2009 and Debian Linux 6.0.x.
Tested on Python 2.5.x to 3.3.2 on the above platforms... (It might work on earlier versions of Python but untested.)
Enjoy finding simple solutions to often very difficult problems...

I am already working on a bash digital oscilloscope, it looks like Python may be just as easy if not easier.
Note the bottom two _traces_ are just for show here...
Enjoy...

Sadly it did not display on here as expected. Oh well worth a try.
Well this snippet was voted down to 0 a couple of weeks ago and it really didn't bother me too much...
Then today, 27-02-2014, it was voted back up again...
To that person who voted it back to 1 again, many thanks from me; you know who you are.
