Weekend Links: Jim Henson Turns 75

Jim Henson was born 75 years ago today! Google is celebrating with a Muppet doodle. If you'd like to spend his birthday sobbing uncontrollably, check out these clips from his 1990 memorial services. As Chris Higgins put it, Big Bird's performance is "devastating."

From Holly, "The Yogurt Made Me Do It!" Or, what exactly is a "gut feeling," and how accurate is it? (I find this fascinating but I can just see some lawyers salivating at the idea of the Yogurt Defense).

Are you familiar with the world's rudest hand gestures? Some of them may mean the opposite thing across the world than where you are (the "thumbs up," for example). The Atlantic takes the job of cataloging them quite seriously, with instructions included, but gesture at your own risk!

In honor of the rainbow I woke up just in time to see yesterday, I bring you the splendor of these Rainbow Prisms.

You guys know I love a good interactive map -- here's a nice little one that's a companion to the PBS series "In Search of Ancient Ireland."

And while you're searching through the mysteries of the British Isles, why not give a fresh look into King Arthur? I really love this site for being a one-stop shop for all thing Arthurian.
*
I just watched a railroad get built today … what did you do? (At first I didn't know what was going on, then I was riveted … no pun intended...)
*
For the working man who has no time to sleep, yes indeed step right up - you can now literally fall asleep on your feet!
*
What would the Teenage Mutant Ninja Turtles look like if they were real? Check out April and the villains then hop over to the artist's site for the turtles themselves. Slight warning of intense images!

Finally, came across this article from the Floss archives and felt I must include it with this weekend's links: a look at some of the geekiest tattoos (and these are seriously, seriously geeky).

Stay tuned - more links on the way tomorrow! In the meantime send your Flossy finds to flossylinks@gmail.com!
