Finally you can see a break down of where all your tax dollars are going.  Now if only I could edit this and put that money spent on defense to being spent on NASA.

What do you think about the disbursement of your tax dollars? Tell us in the comments.

Bubble sort dance

We’ve seen sorting algorithms visualized and auralized, but now it’s time to see them through the spirit of Hungarian folk dance. In a series of four videos (so far), folks at Sapientia University in Romania demonstrate how different sorting algorithms work with numbered people dancing around and arranging themselves from least to greatest.

See them in action in the video below. This one is for Bubble-sort. They move with such zest.

What makes this so interesting to me is it’s terrain detection. To do this in such a small package is quite an impressive feat as well. Although I don’t know that this doesn’t connect wirelessly to a more complicated system. Very impressive either way.
