The more I think about it, it doesnt even have to change randomly. Is there a way to just be able to flip a switch, the display powers up and have it wired to show something that isnt a letter or number? something that could be percieved as "alien" is what I am getting at.
If you could show me how to do this or point me in the right direction it would be awesome
Thanks for all your help
See above. It's very important that each LED have it's own resistor. At the risk of confusing you, I'll mention resistor packs (SIP or DIP) that can save some space if you need a lot of resistors of the same value.
