It's supposed to be a common ground to extend the grounds of my Arduino Uno R3,
I know, not very pretty.  It seems to be not grounding properly which messes up
the display on the 2x16 LCD making it display garbled characters

I have the project using a long breadboard with +/- rails which works as
expected, so, ya, it must be that little red breadboard, though the sockets
seems tight, I'll pick up another one and see if the problem still exists

this is it working with a different breadboard, I though maybe the grounds were
drawing too much power but wouldn't the power draw be the same?
