Recommendation: Unrated.
Description: 13 sort algorithms are proposed; up to 6 can be chosen and compared with one another for various distributions (including killers of supposedly fast algorithms). Speed of animation and speed of compare vs. move can be adjusted. Includes source code and some rough description of the algorithms and their main properties.
Evaluation: Prettier than bar-swapping visualizations. Color dots showing the 'focus of attention' of the algorithm help grasping the algorithm. Includes several variations of the same algorithm to show how small changes in the algorithm can impact its performance over various distributions.
