- -display displayname
- The X display to operate on.
- Operate on a singleplane at a time.
- Flip the screen vertically.
- Flip the screen vertically and horizontally at the same
- Flip small random pieces of the screen instead of the while
- -times number
- Specifies the number of pieces 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

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

totally black. If you pass 0 to -wait, it will wait until you press a key
or mouse button.
