This might be a somewhat strange question.

I had an argument with a windows person and I told him that linux is so much more customization then he told me to prove it and I told him .....
Now I need to make ubuntu black and white to prove linux is better

I want to make ubuntus menus icons, folder icons etc... except the running apps black and white

something like this ??

And stock icons.

So can any one point me in a direction I need to go

Thank you in advanced
