I have a lot on my mind these days, most of which is of minimal interest to anyone (including me). While I get that business sorted out, here is another scattering of links and small thoughts. I suppose if Hidden City was a different kind of site, these would each be individual posts; I suppose that seven years ago, it was.

• Did you ever wonder where Wile E. Coyote kept his giant mallets? It's an odd dimension called hammerspace. It may also be where the ammo is kept in old westerns and B-grade action films.
• Is the Holy Grail located in the mysterious tunnels under a small English town? It's an old story, but there's surprisingly little follow-up. Does the lack of follow-up indicate a cover-up?
• What would happen to the world if every human on the planet vanished tomorrow?
• To my dismay, it appears that Peter Jackson won't be directing The Hobbit after all. That's too bad, as I thought the Lord of the Rings films showed a lot of respect for the source material and remained engrossing and epic films in their own right.
• Looking for a gift for that unrepentant techno-geek in your life? Consider a little something from Motherboard Gifts. They use reclaimed circuit boards to make key chains, business card cases, cuff links, and more.
