Astonish your friends with interesting x effects
xflip [-planes] [-vert] [-oblic] [-fast | -random] [-times number] [-display displayname]
meltdown [-planes] [-display displayname] [-delay x] [-wait n | -wait 0]
This manual page documents briefly the xflip, and meltdown commands. This manual page was written for the Debian GNU/Linux distribution (but may be used by others), because the original program does not have a manual page.
The programs play with the X display, producing some interesting effects. One traditional use of these commands is to have them run and affect someone else's X display, as a practical joke.
-display displayname
The X display to operate on.
-planes
Operate on a singleplane at a time.
-vert
Flip the screen vertically.
-oblic
Flip the screen vertically and horizontally at the same time.
-random
Flip small random peices of the screen instead of the while display.
-times number
Specifies the number of peices of the screen to flip when -random is used. Default is 300.
-delay x
Meltdown may run too fast on fast computers to be fully appreciated; this can be used to slow it down. If specified, every x times the display is updated, a 1 microsecond delay will be inserted. The default is no delay at all. Reasonable values for x are in the 20 to 200 range.
-wait n
Makes meltdown wait for n seconds after the screen is totally black. If you pass 0 to -wait, it will wait until you press a key or mouse button.
