One way glass blocks is just a block that one side has a glass face and blends in on the others!
I would like to give a shout out to <Mine_Diver> for helping me figure out modloader for this version!

You will need Modloader and the mod

2.) Open minecraft.jar
3.) Delete the META-INF folder
4.) Copy the contents of Modloader into your minecraft.jar
5.) Copy the contents of the mod into your minecraft.jar
6.) Close your minecraft.jar and play!
Enjoy!

================== Installation: MultiMC ======================

You will need Modloader and the mod

1.) Create a Alpha 1.2.6 instance and select it
2.) Click edit instance (Should be on the right hand side)
3.) Go to the tab "Version"
4.) Click the button "Add to Minecraft.jar"
5.) Add your Modloader.zip, click open to add it
6.) Click "Add to Minecraft.jar" again
7.) Than add your OneWayGlassBlocks.zip that you downloaded
