[Quest] Four Chords

Okay so in this video of the Axis of Awesome, the pianist says that a lot of popular songs use the same four chords. I'm trying to figure out what those four chords are. If anyone can help me with this quest, then I would greatly appreciate it. Once I can figure out the four chords I'm going on the second part of the quest, which is record a medley of as many songs using the four chords as possible. I have all the information I know so far after the page break.

EDIT: Jake gave me the answer. It's D, G, Bm, A.

[RAGE] Minecraft, Y U no look like this without that awful lag!

I was checking up on my subscriptions and ran across a minecraft creative clone that looks amazing. Normally I wouldn't like this kind of thing, it isn't very unique and rips off minecraft's success, but this is just so FREAKING GORGEOUS! Also unlike other minecraft clones, and minecraft itself for that matter, I saw no lag here. I'm going to try to imbed the video after the page break, but if I fail at that, here's the link

[Review] Hack/Mine Mod

So after the server computer was snagged by my aunt for the weekend, I decided to play some Hack/Mine to review it. The review is below the page break. I kind of want Fraps so I can record videos of the computer.

[Query] Anyone up for an all out class war?

I realize that this post will be controversial, so if you don't want to read this, just skip the post and forget about it. If you feel like reading it anyway, go ahead; it's your funeral (Or mine: too soon to tell)

[Challenge] A List of All The Ones Posted So Far

A winner is you.

Now a lot of you may be asking, "Why all the challenges?" The reason is because, quite honestly, Minecraft gets dull after a little bit. Challenges add new objectives to complete to the game, which makes it fun again. So I put together a list of all the challenges that I have posted so far (click on a challenge to go to the original post for it).

Mrs. DeLuca's Tests

I  made a PowerPoint (took me two and a half hours[doesn't matter cause I was procrastinating anyways]) for Mrs.DeLuca, you guys review it.

Minetest

Beautiful Graphics minus the lag.

Minetest is a Minecraft clone. The difference is it is written in C++ not Java. It also has much cleaner code than Minecraft. I'm going to download and try it when I get time and write a review. At the moment it is lacking a lot of features that Minecraft has though.

[Challenge] City Construction

Remember when the goal was to make a city and go to the moon in the Bukkit server? This is pretty much the same thing but with a storyline, guidelines, and objectives. There are multiple levels of difficulties available. Here is the thread, comment on the blog if we should try to band together and complete this challenge.

[Challenge] The Tree Spirit

I'm going to pass on this challenge personally, but if anyone wants to try it out then go ahead. Post pics to gain respect points from everyone for doing this interesting challenge. The rules are described in this thread. Also I need to stop calling them threads since officially they're called topics by the forums.
