Okay. I need a series of logo's like Adobe CS3.

Basically I am working on programs for the same thing in general but they do a different thing. So I need a logo theme but I can't think.

Like I said like Adobe CS3 has differenct coloured boxes with initials of the program in the, like

Fl, Dw, Fw, Ps etc.

Anybody have any good ideas? Please dont like me to logo sites unless you are reffering to a logo on there. Thanks
