Title: Vis overlay

You might want to consider drawing the vis overlay before the ants etc. I swapped it around and I think it's much more useful to draw the ants last since otherwise the tiling I do (even with low alpha) makes it too hard to see the ants. Of course you are entirely welcome to ignore this :)
