If you like @peekay123 's cool RGB Matrix projects you may be interested in making animations. I built this little Excel worksheet that allows you to simply paint a “Matrix” with colors and it will build a BitMap for you!
So easy, my kids can use it.
Looks like this:
And as you can see you get a table of values by placing a “1” in the color layer you want.
I thought folks may want to use it, or even better, improve it. I cannot upload an excel file so if you want I will email it to you if you PM me.
