Seeing the LED board before it exists

Waiting for parts is the slow part of any hardware project. I wanted to see what the board would look like before I owned one, so the web app got a preview.

The preview draws the display the way the real panel will: 128 by 64 dots, with the same fonts, colors, and layout. It animates too. Pages change on the same timer, and the ticker scrolls along the bottom.

That turned out to matter more than I expected:

The same night I put together the list of parts to order, and started waiting.
