I have downloaded the rainmeter skin which is a small bar that looks exactly like the xbox 360 achievement.

And I want to here everyone's ideas for cool achievements.

I have ones like

deleted system 32
1 tb of porn downloaded
48 hours of nonstop gameplay

So yah

make up your own achievements and you can download the skin too if you have rainmeter.
