An implementation of the DaisyWorld has outlined by Stull in Meteorology for Scientists and Engineers, 2nd ed., Brooks-Cole (2000). On this world, there are two kinds of plants: white daisies and black daisies. These plants, along with bare ground, cover the planet. There is a fixed death rate, as well as a fixed value for horizontal temperature transport. The plants, however, have different albedos.

You get to set the luminosity using the thumbwheel. When you click the Start button, the simulation begins. When a steady state is reached, the percentage of cover by the daisies and bare ground will be listed, and the final surface temperature will be shown on the thermometer.

In this version, a separate chart window will pop up that allows you to keep track of your experiments!
