Bouncing balls for an X windows background. Known not work to with tvtwm, may not work with other virtual desktop systems. Works with twm and olwm. Can take a lot of cpu and X bandwidth. Alter the Makefile as appropriate and type: make To run type: xballs Options are: -d hostname display on hostname -n number number of balls (6 by default) -r radius radius of balls -c coeff coefficient of restitution (sp?) -t percent percentage of balls generated at the to of the screen The program is a bit 'rough round the edges' The balls interact with the mouse pointer, but not with each other (I'm sure there is a simple method for this using matrices but I havn't been able to find it) The more balls you have, the more cpu power used. (I would suggest a maximum of about 6 for a Sun 3 and 12 for a Sun 4) Bernard Hatt bmh@terminus.ericsson.se
