The code to include this applet looks as follows:
<APPLET CODE="Snow.class" WIDTH=250 HEIGHT=140>
<PARAM NAME=image VALUE="christmas.gif">
</APPLET>
The width and height here should be at least the width and height of the image you use, in pixels. The image parameter specifies the background image to use.
NOTE: The snow will land on any pixel which is NOT perfectly black (perfect black has red, green, and blue components all 0).
