Every so often, someone comes up with the "new" idea that we should update the Lojbanistan flag. I don't think any of these resurgences ever had any actual effect, although Bridi Man is one of those flag updates that is used- just not as the flag.
This is not another call to update.
I just saw a video by Numberphile about the most mathematical flag of any nation, the flag of the Kingdom of Nepal. It's rather interesting, since the entire flag is described in purely mathematical terms with absolutely no units of any sort.
I think it would be interesting to have our flag described in the same manner.
