Hacking the Browser - Bookmarklets

This week, I made a bookmarks that works against users. It will replace the cursor with a emoji image, and whenever users click the mouse, it will show more emoji images to block users sight. It's called "Raining Cats and Dogs"

Here's the vimeo video

For interesting bookmarklets, I didn't find an existing example, but I think it will be very cool to have a bookmarklet that hides your cursor when you click the mouse and show you the cursor when you click again. I think the way to implement it this:

var toggle = false;

document.getElementsByTagName('body')[0].onclick = function(){

if (toggle == false){

document.getElementsByTagName('body')[0].style = "cursor: none;"

toggle = true;




document.getElementsByTagName('body')[0].style = "cursor: auto;"

toggle = false;
