Great work. Reminds me of Choc, an implementation of Bret Victor's Learnable Programming: http://www.fullstack.io/choc/ I'm really interested in solutions for visually explaining what an algorithm does. Anyone have any other resources they like?

This came up on HN a couple of weeks back - http://www.algomation.com/

A few sorting algorithms - http://www.sorting-algorithms.com/

Visualization of Path-Finding Algorithms - http://qiao.github.io/PathFinding.js/visual/

Lastly, Mike Bostock (creator of D3) has a really cool bunch of algorithms over at his blog - http://bost.ocks.org/mike/

http://www.algomation.com/ has a lot of algorithms explained visually.

I also maintain a playlist with interactive explanations, which might be of your interest: https://gibbon.co/Steven/interactive-math-for-lasting-insigh...

VisuAlgo is also very nice. http://www.comp.nus.edu.sg/~stevenha/visualization/index.htm...

A friend posted this funny video series of sorting algorithms interpreted through eastern european folk dance today I just have to share! https://www.youtube.com/user/AlgoRythmics/videos

I like Cortesi's take on algorithm visualization: http://corte.si/posts/code/visualisingsorting/index.html

My sense is that animated visualizations are good at giving an intuitive sense about performance, but static visualizations are better for understanding how an algorithm works. If I was implementing a sorting algorithm I'd rather have one of Cortesi's visualizations on hand.

"A* " may be one of the most un-Google-able algorithm names I've come across, since the {asterisk} is used as a wildcard too. (Edit: and is significant for formatting here too.)

As of this post, Googling "A* algorithm" gives more relevant hits about the algorithm than the experience I had many years ago when I tried to learn about it, but it still uses * as a wildcard so you get various other algorithm pages mixed in there too. Trying "A\* algorithm" seems to yield even worse results, which is counterintuitive to the programmers who are most likely to try escaping metacharacters in queries...

Search phonetically, "A star", even better include "search" and "algorithm"!

Very cool list, thanks for sharing.
