For those that wish to move beyond the medieval realm of vanilla Minecraft! Take note, many of these texture packs change how the Minecraft world looks considerably, it's very easy to get confused.
I would recommend using these only for single player, creative worlds, or as a fundamental server requirement to avoid potential misunderstandings. Some of the texture packs will recommend additional mods to download, so be sure to follow their instructions.

If you're as old as I am, you remember the days spending hours playing games on your brick Gameboy earning neck cramps and replacing the 4 AA batteries that it required. This texture pack takes you way back.. It doesn't just have the same green monochrome color theme, but the blocks themselves have that classic Nintendo art style.
Have you ever wanted to go to the moon? Eat cheese on the moon? Dream of electric sheep? A very old pack that I am happy to see still around and updated. The_Fool76 also has 3 other texture packs to take a look at, which you will see in the link provided.
Another post-apocalyptic world only more depressing. All hope is lost and all that's left are the ashy, and sometimes mutated, remains of the past. Started by the famous Doku and has been continued by fans.
Sometimes, a cookie is enough sugar. Sometimes it's not and you want to go full-on diabetic. High on Sugar turns Minecraft into an adorably girly candy land. A wonderfully sweet work of art that also includes support for Random Mobs.
The best for last, Glimmar's Steampunk has a ridiculous amount of textures to customize the texture pack to your own needs. The level of detail blows the mind, it doesn't look it but it really is just 32x32 in size. I can't write enough to say how outstanding this texture pack is, so you'll have to see it for yourself.
