Hope you are using Firefox, simply great and ubiquitous browser. Did you ever try typing this into your browser's address field. Try it and see for yourself:

Here is a nice preview:



I use GTK-QT engine. So you may find my browser slightly different.

Enjoy :-)

This will make you jump out of your chairs. The subject of states and transitions looks a lot more interesting. While compiling gcc you get this as a part of output to console:
