The taskbar has been made transparent with the Fadebar app by
nookian or similar. App get:
Fadebar
Apparently you need a visual style that works well with Fadebar to make it look good.
nookian provides one here:
LunaInspirat
In the quicklaunch I see an icon with a red moon. I guessing this may be Shutoff, also by
nookian. I use this myself and it's really good. App get:
Shutoff
The "worded" icons for a dock are either
BASIC5 by
Otisbee,
The Kobhens by
Robert Urso (from which
BASIC5 is based) or a derivative thereof.
Lucid Icons by
leechiahan are somewhat similar and may be of interest. Icons get:
BASIC5

Since it is clear s/he is using
Winamp, I believe the "now playing" like widget on the bottom left is a skin for
CDArt Display. It comes as a stand alone
install or as a plugin for
Winamp,
foobar2000 or
Media Monkey. I recommend downloading the
CAD 2.0 beta 5 so you can use some of the newer and
better skins for it.
Otisbee has a very nice selection over at
Deviantart.
(After installing CAD 2.0 you associate it with which ever player you have. If
you would like it to also open with another one of your players, download the appropriate plugin.) App+Skins get:
CAD 2.0 beta 5
Otisbee CAD Skins
Winamp Modern Skins
As mentioned above, the weather widget, to-do list, etc. can be achieved with
Rainmeter,
Samurize or similar. If you have never
used such tools, you may prefer to download the impressive
Enigma desktop suite by
Kaelri. It should give you some sort of framework to start
fiddling with these tools. Apps get:
Rainmeter
Samurize
Enigma
Not sure how s/he has titles next to the music and pictures icons. I assume it's either Objectdock, Rocketdock, XWindowsDock or
something similar. As for that wallpaper... HERE, knock yourself out. I'm sure you'll find something.
If you look around, I am sure there are many other solutions than the ones I have mentioned. Good luck.
