RedRay - An X-Ray mod/texture pack for Minecraft

Powered by Redstone is working on it's own mod, called RedRay. This mod allows you to see through various blocks to find ores faster on single and multiplayer. The great part about this is that it requires no mods to be installed. It is seen by Minecraft as a texture pack, so just put it in your texture pack folder to use. The only catch is that you need to change your texture pack every time you want to use the X Ray, so a mod that lets you switch texture packs on the fly (like OptiFine) are recommended.

It looks like this in your Texture Pack options.
