https://cohost.org/roguecache just made a new solarpunk logo; i think it's very well designed and keeps the simplicity while still keeping sun, nature and technology meanings
Is it just me or dose this one looks a bit like the depressed Form of v1 (I love v1 its part of my punk-jacket). The down hanging leafs combined with the darker colors give me a more sad vibe like if the plant needs watering or something.
This would lend itself to stencils pretty well though (one color, no islands), especially with a touch of spray adhesive on the back. I've done the symbol from one of the more common solarpunk flags, and getting the blank spot inside the gear positioned would be a little finicky if doing graffiti.
You'd want to bridge the corners there, to make it all one piece, if you wanted to be able to put it up quickly. I was just painting a laptop so I had plenty of time to fuss with it.
Looks nice but probably too many details to work at smaller sizes. A single large leaf instead of the whole leafy stem would convey the same visual concept.
