Crowling the web, i found a weird signature that a user had. It displayed memory usage, cpu usage and some other stats on his pc. I thought it was weird and it might have been a custom thingy he did and hosted. Soon i found l33tsig. This is a service where you download and install a client of the service that every now and then it uploads such stats (your cpu usage, memory usage etc) and when the sig is displayed it shows the latest stats. Anyways i think you should give it a look and install if you think it’s worth it. I don’t think i will but  you should see for your self.
