Where did you get the wallpaper from?

And what karamba theme is the clock?

I got this wallpaper a while back on deviantart.

Unfortunately, the artist seems to have been inactive for a very long time (paid2smile.deviantart.com), and her gallery of art is now only accessable by (paid) subscription members - which I am not.

I've uploaded the wallpaper to http://www.users.on.net/~j.h.y.chan.

As for the clock, I did not spend time looking for (or making my own) superkaramba theme.
It's actually the clock applet for kicker - an additional top panel was configured to occupy a large space in the top right corner to achieve this effect.
It's quick and effective, but occasionally gets annoying when mousing over the top edge of the desktop. This clock is probably not an option for people who use desktop icons though.

A relatively simple superkaramba theme could probably be made to do a far better job.

hi, Welcome to Arch :D
is that conky
where I can find the script?

Yep it's conky. My own config there with a *VERY* badly coded bash script for the weather info.

if you want to try it anyway, i've uploaded the files to:
