FrogPond challenges the user to design experiments that will establish the cause of deformities in a model frog population.

Download the FrogPond Application:

FrogPond for MacOS
  • To run FrogPond for the first time, you may need to hold down the control key, click on the FrogPond icon, and select Open from the popup menu that appears. (This is necessary because I am not a registered developer with Apple.)
FrogPond for Windows
  • Do not delete the folder called FrogPond Libs. FrogPond needs it to work properly.
  • The first time you open the FrogPond application on Windows you may see a dialog box titled “This application may depend on other compressed files in this folder.” Click the Extract All button (not the Run button). If you just click the Run button, you’ll get a Runtime Error message.

FrogPond is free. You may give it to anyone you like, so long as you distribute it as a stand-alone application. You may not sell it. You may not include it in a collection with other software, regardless of whether you are selling the collection or giving it away.

I make no warranties or guarantees about the quality of FrogPond, or the accuracy of the simulations it runs. Use it in good health, but at your own risk.
