OP here. Yes, there are whole bunch of DIY wordclocks. And I would encourage anyone that is interested in the challenge. That's how I started on this route.

I've really enjoyed the process of figuring out how to manufacture these. To me that is an interesting challenge.

I've only found one other "high end" word clock on the market. Personally, I don't like their aesthetics. So I decided to make my own. I realize that many people may not like my aesthetics. That's art and style. To each his/her own.
