Steve recently mentioned a video showing how the quiksort algorithm works, including an explanation from Bobby regarding the need for the final seconds to be sure that NaN values are sorted correctly.
With much amusement, many of us from MathWorks recently viewed this video depicting the quiksort algorithm in dance. I don't think you'll see a MATLAB animation quite like this!
If you are interested in similar visual depictions of other sorting algorithms, check out this link.
In addition to these animations showing off mathematical algorithms, I have also enjoyed listening to and trying my hand at change ringing. I find similar points of intersection between my love of math and my interest in other art forms as well. Also check out the 17 regular tilings of the plane.
Do you have similar links between some interesting math and art? Let me know here.
