Graphs

[delir!um]

Hello everybody,

I want to know how they display those Graphs on their Desktops. What I
mean? You can take a look on it in here -

screen_type=2&screen_id=246174509415db6dc18371&m=screen . I mean those
half-transparent graphs showing you CPU and so on. Do they have some
Tools for it? They also have calendars on their Desktops, I want to have
them too ;-) And the terminal seems to be transparent either, how do
they do this?

Kind regards,
delirium
