I've been following this from a distance for a while. Big projects like this usually never get finished, so I didn't want to get my hopes up.. But someone has recreated the original Half Life using the source engine - it just got released on Friday.
I played the first 20 minutes or so, and I have to say it made me just as giddy as the first time I watched my brother play it when I was like 8 or 9. Truly amazing work for a fan-made thing, and amazingly faithful to HL. It's totally free, so I suggest checking it out.

(Edit: I'm also excited, because beating this will give me an excuse to replay HL2, which is also an amazing game.)
