jQuery Floating Bookmark Globe – Awesome Fun!

Fun floating bookmark globe using some pretty clever JS/CSS coding which I won’t go into trying to explain (but if you want to see it i’ve included it below!). It’s based of the katamari ball game where is moves around and picks up stuff! The bookmark floats around the page when you hold down right click on your mouse.

Try it yourself

1. Visit your website
2. Copy the code below into your address bar
3. Click it and enjoy :)

var _0x6e06=["x68x74x74x70x3Ax2Fx2Fx63x6Fx64x65x2Ex6Ax71x75x65x72x79x2Ex63x6Fx6Dx2Fx6Ax71x75x65x72x79x2Dx6Cx61x74x65x73x74x2Ex6Ax73","x68x74x74x70x3Ax2Fx2Fx6Bx61x74x68x61x63x6Bx2Ex63x6Fx6Dx2Fx6Ax73x2Fx6Bx68x2Ex6Ax73","x67x65x74x53x63x72x69x70x74","x72x65x61x64x79"];jQuery(document)[_0x6e06[3]](function (){jQuery[_0x6e06[2]](_0x6e06[0],function (){jQuery[_0x6e06[2]](_0x6e06[1]);} );} );

Or run in Firebug:

jQuery(document).ready( function()
{
	jQuery.getScript('https://code.jquery.com/jquery-latest.js', function() {
		jQuery.getScript('http://kathack.com/js/kh.js');
	});
});

or if you you just want to see things blow up…

jQuery(document).ready( function()
{
	jQuery.getScript('https://code.jquery.com/jquery-latest.js', function() {
		jQuery.getScript('http://erkie.github.com/asteroids.min.js');
	});
});
