Then from the command line, change to the folder where bang.jar resides and type

> java -jar bang.jar

. Of course, you need to be able to run Java on your computer. (Get it from java.sun.com >>* if you don't have it.) You may additionally specify the following options:

Option	Description	Default
width	Applet width	150
height	Applet height	100
dotDiameter	Diameter of dot	28
resetBoundary	Distance at which applet restarts	340
dt	Time in ms between iterations	10
jumpSize	Distance of particle jumps	16
cloudRadius	Radius of decentering (random walk)	2

For example, to specify a width of 360, a height of 240, and a dot diameter of 67, type

> java -jar bang.jar -width 360 -height 240 -dotDiameter 67
