Change the "look" of Minecraft with texture packs!

I have been playing Minecraft with a texture pack that looks VIKING!
Texture packs are easy to add and change.
First, you need to know where to find your Minecraft data folder.
Run Minecraft and click the button "Mods and Texture Packs" from the main screen.

This will take you to the Mod and Texture Pack selection screen.

Click on the locate folder button. It will open the folder.

It will empty until you add texture pack.
Note how ALL the packs are zipped folders.  This is how they download and all you have to do is move them here!  NO unzipping required.

There is a very good selection of texture packs on the Minecraft Wiki page
Minecraft Wiki.net Texture_Packs
The one I like best is the NorseCraft one
You can find a links to the down load pages.

Make a note of the version compatibility.
Each time there is a Minecraft version update you may have to down load an updated texture pack.
For instance, when Minecraft 1.7 with pistons came out... the texture back did not have an image for them.
Once you down load a texture pack ZIP file, simply move it to your Minecraft texture pack folder.
Now, when you are at the Main Menu and select Mods and Texture Packs Button, your down loaded packs are available.

Highlight the one you want, default is still available and click done.
This will take you back to the Main Menu and depending on the Texture Pack, you may seen changes already!

Now you can select Player Mode and enjoy the new look to Minecraft.
