This isn't entirely an invention, so I'm happy for it to be
MFDd, unless it counts as an invented way to amuse onself
slightly.
I have just noticed a strange and curious effect on the LCD
screen of my MacBook Pro (an old one), and thought it
might interest or puzzle others.
If you press
(firmly but not too hard) on the screen with a
fingertip, and then suddenly remove your fingertip (from
the screen, not from your finger), you get a sort of ripple
effect. This is not the interesting part. The "ripple" is
caused, I presume, by the slight compression and distortion
of the LCD screen.
Now the interesting part. This works best if the screen is
showing white (like the blank space on this page). Press
the screen at two points, an inch or two apart, then
suddenly remove one fingertip. What happens (at least on
my screen) is that a little shadow zips across the screen
from the place you just removed your finger from, to the
other (still pressing) finger.
No idea if it works on other screens. But it amused me.

You need to get out more. |

Wait - the alien hegemonising steam-engine
enthusiast is telling me I need to get out more? |
|
| |
Yes, we are. You should be worried. Very worried. |
|
| |
True. But I bet you've tried the thing with the
fingers and the screen. |

I've tried and it wasn't terribly successful. There was
a little sort of ripple thing but not much. It was on a
resistive touchscreen, with a white background. |

No, it works better on a non-touchscreen LCD monitor ... oops. |
