Play a Webpage Display Prank in Google Chrome

Are you looking for a fun but innocent prank to play on someone who loves using Google Chrome? If so then you may want to have a closer look at the Upside Down extension for Chrome.


Here is our example webpage before starting the prank…looking all “normal like”.


Upside Down in Action

As soon as the extension has been installed you are ready to go. If you had a webpage open before installing the extension you will only need to refresh the page. As soon as the page has been refreshed or a new one is opened everything is going to look messed up very quickly. With the default setting there are five different “looks” available.

To cycle through the five “looks” use the “Windows Key + Semicolon” or “Command + Semicolon” to toggle through them. On the sixth toggle the webpage will revert to normal (toggling afterwards starts the whole process again). Here are the five “looks” available…







There are options available for the extension where you can focus on just a specific effect or a group of effects. You can also enable a “Grayscale Effect” and even set a delay timer (a definite “evil touch”)! Think of the fun and surprised looks that await…



If you have been looking for a fun and unexpected prank for your favorite Google Chrome fan then this just might be what you have been looking for. Get ready to sit back and watch the fun.

    This actually isn’t as frustrating as you might expect since the mouse still moves as expected (though the scroll wheel is inverted). Using the screen rotation functions of the display adapter drivers also inverts the mouse movement which becomes truly *frustrating*. >:|

    It should be noted that this just inverts the output of the renderer, the text is still the normal text, so you can copy and paste as usual. It does not replace the text with UNICODE characters that look like upside-down versions of the Western character set like those created by “upside down text generators”.

    Oh, and it might be fun to try this prank in conjunction with some of those backwards sites like Google Backwards.
