I'm officially taking a day off today to get ready for the holidays ... but it's hard to stay out of the blogosphere entirely, especially when my science-minded son is playing so many cool YouTube videos on the home computer. So I've collected a few geeky clips to add some science content to your pre-Christmas weekend. The one above is from "recreational mathemusician" Vi Hart, and was featured on NPR's "Krulwich Wonders" blog. Hart has lots more where that came from.
Last week I linked to a video that illustrates the workings of the once-mysterious ancient Greek Antikythera computing device, using Lego blocks. In case you didn't see it the first time around, here it is again:
Today I noticed that there's a behind-the-scenes video as well:
My son countered with this TV-commercial-like video for a Turing machine made of Lego blocks. Well played, sir:
Have you detected a theme here? All these videos illustrate the workings of math and science using stop-action animation. To close out this video roundup, here's a just-for-fun stop-action project titled "Insert Coin" that looks as if it took a lot of work. Thanks to Paul Hsieh at GeekPress for pointing it out:

So all those years in school I was doing it right! Revenge!
Here's my favorite scifi vid from the YouTube-- you have to sign up to see it though, because of some adult themes. It's called We Are the Strange and was made in a basement utilizing stop-motion, models, CG effects and old-school animation. Pretty wild mash-up. Don't expect the plot to make much sense. It's just for fun.

I am sooooooo glad that there are people in the world whose brainpower overflows their cranium. And that some of these people choose to use their time to THINK, CREATE and SHARE! All these made me smile in unique and creative ways and added to the Joy of the Holiday! And I hope you feel the good karma flowing from me to you in this Season of Good Will!
