Really great addition to the game. I hope that in the future, they will be more varied, since the TNT would really only trick you one time. They could have variations where there's a trap near the entrance to the room above instead, or even place traps around the perimeter of the pyramid. A little variation would help to encourage people to have to be alert when exploring these.
They might also make good candidates for generating sort of sandstone-based mini-strongholds underneath in very rare circumstances instead of the simple chest room.
Dude it's real... Sorry I had some serious doubts.
Unfortunately I knew where the TNT was. but I fell and landed on the presureplate. But then when nothing happened I thought "Oh I see... that was just put there by the player to confuse us. So i look through the chests and didn't see much and then 'BOOM" I well I didn't die because I was on creative but still. lol
Of the changes made to Minecraft with this snapshot, the Pyramids are one of the things that I sort of like the most. I'm pretty sure they've been working on this for awhile, but still it nice to see it finally implemented (I sort of guessed they would do something like this when the hieroglyphic blocks were first introduced).
Variations in the overall design and some traps would be useful, but even so I'm glad to see this added to the game.
--You know what, I'm getting so tired of living in my mineshaft at the beginning of the game while planning out the design of my house and gathering the materials that I'm going to live in these desert tombs every time I start a new game!! It's stylish, pre-built, and I get free tnt, bonemeal and gold!
