Log Pot Simulation w/ Parallel Resistor

Just for laughs, I wrote a little Java applet that graphs the output of
an attenuating pot with either ;
A. A second parallel resistor between wiper and ground
B. Wiper going to an op-omp summing node.

You can enter the input voltage, the pot value and the parallel resistor
value and it will graph the output of a perfect linear pot, a perfect
log (base 10) pot, and a linear pot with the parallel resistor.

Some of you may find it helpful when deciding what kind of response you
want from your summing nodes...
