That's one hell of a great texture pack for Minecraft in this amusing short by Wolv21. Yes, there's a creeper involved.
Darn, I was hoping it was an actual texture pack.
Let's face it — Minecraft's graphics are crap.
I'd really like to see someone make a Minecraft-like game, but with realistic/modern graphics. I get the whole pixel-art, retro, blocky style.. but I think the world of Minecraft is not a good application for it. It would be 10x more immersive if the graphics were improved.
