it looked like both to me, the dock at the bottom and the start at the top.. then again, being a visual person I recognise icons by the default windows ones so if it's changed.. I won't recognise them being windows... (and I didn't full view your desktop =x)
for the visual skin theme thing....install a hacked version of your uxtheme.dll which allows you to install themes on windows....normally you've only got windows xp and classic (lame & lamer) ... the hacked dll allows ya to install whatever theme ya want....
at the bottom that's a program called object dock.....dock comes from mac's ... super cool program where you can have your shortcuts whenever u need em
Your dock icons are amazing, totally urban art styled.
