I think that must be sphinxcore's logo.
He's the maintainer of the /r/cuberite subreddit.
Green or purple are also good colours, blue or orange are bad, as they are taken by Bukkit and Spigot.
It's dead simple, but with that color combination, I think I can say it has to be kinda unique.
Wow, that's a really nice Eschercube, again. While yeah, it does look awesome, that'd kinda be like having the Mona Lisa for the logo. I absolutely love it, so if you'd want that, go for that.
I wonder if someone could make a grassblock-based Eschercube

Just realised there's even kinda MineCraft reference in the name: MC Escher

Hehehe! That would be so awesome!

If you like this logo, you can have it on any color you can imagine

I'm not so good with graphics, already the Eschercube took me longer than I'd like to admit.
So I won't be even attempting the grassblock Eschercube. Just asking if someone more handy with PS / AI could do it.
That's a bit too close to the Mercedes logo

Updated it. Doesn't look that much like the Mercedes logo.
