I got my hands on two old very large 12x12 cm ( 4.6x4.6 inch) panel meters which were never been used. The display was still blank. The design for the display was made in Adobe Illustrator and printed on sticker material which i laminated with matt laminator pouches.
I really like this project - I can imagine an array of meters reading tides, precipitation probability, percent cloud cover, expected high and low daily temperature, snowfall predictions, and others, all scraped from web weather resources.
A while back, I was working on a similar concept that showed the daily movement of my retirement portfolio (+/- 5% scale). Then, the global economy melted down, and the thing would have just sat on the left end stop for months at a time, so I dropped the idea.
Yours is a much better application!
