When i first saw the mod, i didn't know what the thumbnail meant, and when i saw the explanation and the wikipedia page, i tought "why didn't he made at least a more pixelated version? this doesn't look like a logo", so i decided to make a more minecraft-y version, and i came up with this:

If anyone could upload it, i would like it a lot.
(Sorry for the bad english, i'm not a native speaker)

I'm also working on a gallery image version, with more cores.

uhhh... hello? @malte0811 , do you like this?

Sorry, I am not interested in changing the logo. For this sort of thing you should generally contact the mod dev before you put any work into it.
