Game Theory .net resource, Generating Random Sequences, featured as a Teaching Idea and Application in the Journal of Statistics Education.

From Teaching Bits:
This Mathlet allows the user to input a sequence of 0's and 1's of length 20 and then tests the sequence for randomness using three tests: Kolmogorov-Smirnov, Wald-Wolfowitz, and Mann-Whitney. An overall assessment of how likely the sequence was generated randomly is given, as well as basic information on how the tests work. .
