Found this awesome tutorial for quickly making a spiral staircase, check it out.
This is the launch trailer for Dragon Age: Origins. If you haven't heard of it, it's a dungeon crawler RPG for the PC, Xbox 360, and PS3 from Bioware, the makers of Baldur's Gate II, Mass Effect, and Star Wars: Knights of the Old Republic.
It's coming out one week from today and if you like fantasy themes and/or dungeon crawler RPGs then this game is something you should check out. You get to create your own hero and choose their "origin", or backstory that you get to play through and then collect a party of heroes to fight off a group of monsters known as the Dark Spawn. If you've been itching for a great RPG like I have been, this may be the game we've been waiting for.
Also, the PC version of the game will include a full toolset for creating your own scenarios, including the ability to create your own cinematics and record your own dialogue. Check out this link to see it:
