Forgot to mention that I uploaded Black Mesa Source's first teaser yesterday. It is pretty damn cool. For those of you that aren't quite sure what Black Mesa Source is, I'll give another brief summary:

A group, called Black Mesa Source, believes that HL:Source cut far short of the Source Engine technology. Basically, when HL:Source was released by Valve, there was barely any change from the original Half-life. There were a couple features that improved the overall gameplay. For instance, if an enemy is close enough to a wall, you can pin the enemy against the wall with an arrow. WOOOAAH! That defintely makes Half-life worth playing again !

Anyways, check out the teaser here: http://www.gamespot.com/users/jlr2k8/video
