Here’s a link I found out that you can use to check your pagerank. If you already installed Google Toolbar, you know you didn’t need this tool ;)
Check Pagerank

And for this one, this tool can check your socialmeter. Try it.
Check Socialmeter

This cool trick is kinda pointless, but it can amuse you for a while :D
Here’s how:
Copy & Paste this code below to your url bar. And you will see that all of the images in the previous page you open will start swirling around. Cool, eh?

javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200;DI=document.images; DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style;DIS.position=’absolute’; DIS.left=Math.sin (R*x1+i*x2+x3)*x4+x5;DIS.top=Math.cos(R*y1+i*y2+y3)*y4+y5}R++}setInterval(’A()’,5); void(0);
