it seems to appear like a digital watch when "lit" up.. im assuming it should look about the same in light... i don't really know though... if it doesn't work, i will try something else... thats whats good about doing it as a hobby!!! no deadlines and as long as its cheap, i can try different things until i find something i like.. i cant remember now, but i think i got these displays for around $1 each, and then i got a couple that are 2.5 digits ( 1.8.8) and some LED backlights for them for a couple bucks a set too.

i will try to post a video of what the display is doing.. then maybe someone will have an idea of what is actually happening....
