The crystal shape of a snowflake depends on several parameters,
including temperature. In this applet, you can explore how snowflake
crystal shapes depend on temperature -- click repeatedly in one of the
temperature zones (between the lines). Then move your cursor to a
different temperature zone and click some more. You may combine up to
3 different shapes before resetting (by clicking below the cloud).
