correlated random numbers

For the block course "Grundlagen des Experimentierens" I programmed a small CouchDB based online data acquisition and live visualisation tool. A toy model featuring jquery and flot can be found here.

On the right you enter pairs of numbers (or use the provided (pseudo) random number generator), on the left you'll get a scatter plot. The PRNG gives you 500 pairs of numbers, approximately Gaussian with a standard deviation of 15, centered at (50,50). The lineare correlation coefficient is set to -0.6, but will be adjustable soon.
