Recently Mojang relase 12w22a Snapshot,this were cool,there were

• Trading with villagers has been updated
  
• Enchantment system has been rebalanced
  
• A new Redstone-activating block
  
• Better Creative inventory
  
• Pausing should work in single-player now
  
• Some minor terrain changes
  
• Added an o adventureo game mode (/gamemode 2), but requires more work
  
• A lot of smaller changes and fixes
  

But this means that the textures will change, there were a new menu and Emeralds.

The textures of Minecraft 1.2.5 will not work as same as the new snapshot but I find a few textures for your minecraft 12w22a Snapshot

Here are the Links:

1.Hancraft

2.Dokucraft(HD)

3.Ravand's Realistic Texture Pack(HD)

Enjoy they! For me Hancraft is the best.
