I once suggested a similar project at our company. One of our products is labelled in braille. For technical reasons it was the easiest way to drill holes in the front plate and stick a transparent plastic insert through from the back.
My suggestion was to add a few blue LEDs behind it to light up those braille dots. It would have been meaningless for the intended user - but it would have looked way cool!
Yep. That one was made by a guy who made all kinds of warning plates for their plant, and legal & corporate requirements were that every sign has to have braille on it. I don't think the department requesting that sign from their sign-making-department had this on their screens...
There's also no way for someone who needs Braille to actually DO the "puzzle". The other words don't have Braille, the map appears to be flat. Terrible design.
