Here's a trick for you: Make your computer do 1000 things at once, then make it appear to do 0. Simply type Ctrl + Alt + Shift while simultaneously clicking the Refresh button, the Tab key, and the Windows Key on Windows, or CMD + Shift + Option while simultaneously clicking the Refresh button, the Tab key, and the Command Key on Mac.
Or, if you're feeling really advanced, try this: Make your computer display 1000 different images at once, each one of a cat in a different pose. Simply use a CSS file and some JavaScript magic, then refresh your page 1000 times in 1 second.
