Afternoon Delight is a daily diversion for when you’re just back from lunch, but not quite ready to get back to work. Check back tomorrow at 1 p.m. for the next one.

Sometimes, there’s a whispy cloud hovering over White Rock Lake or tendrils  of mist in low-lying areas out in the countryside, but we rarely get much serious fog action here in North Texas. I mean, real fog, the little-cat-feet-squatting-down-and-turning-into-a-thick-fat-furball kind of thing.

Now, San Francisco, that’s a whole nother climate. I’ve been there in the blazing dead of summer, and there still was fog rolling in when the sun rose that morning. Simon Christen, who lives there, started filming the town — and discovered how much like an ocean the fog really acts with waves and breakers and receding tides.

So, yes, it’s another time-lapse video for Afternoon Delight, one we’ve borrowed from an NPR.org blog.  But if you’re not all that surprised here by the ocean-like clouds rolling along, zip forward to the one-minute mark for what looks like some of the most gorgeous rock-concert, dry-ice effect footage around.
