This is an example of how an idea progresses.
I tried a slightly different version based on the "Ukraine since 2014" sign Blazoes posted
Rather than use 1,2,3,4 which only ever represented a general idea of the quantity of mines in a hex, not their actual number this just includes a bar scale at the top to indicate density
The one issue I have with them is how much of the hex the triangular version occupied
So I tried a square version
I still felt it was too large and it was the word MINES that was making it that way so tried and even more minimalist version
and that lead to this which is even smaller
which lead back to a yellow alternative
.........and that lead back to an alternate yellow triangle which brings us back to size
Then we get to three versions of full minimalist
But with full minimalist the word MINES can be added back
and yet another..... it works for summer and winter which means it will work for desert too
AND FINALLY.............
A revised version on the right, of the first one with the first attempt on the left
it's a bit smaller than the sixth one....a couple of pixels makes a big difference sometimes at this scale
...and in red
Feedback welcome
