This is a very basic dot matrix design, would be great to see what people can do with it!

Switch guide:

Row 1: Y1 - Y6

Row 2: Y7 - Y12

Row 3: X1 - X5

Neat, but dot matrix displays really need an active driver. The driver should enable one column at a time and power the appropriate row lines for that column. I'll be impressed if you can cram all that into EC. ;) There may also be a problem with persistence of vision.

I wrote that, then found I actually did it 2 years ago. I've learned to relax since then!
