Simple illustration for website by jokerkiller

Project Description:
I need a simple technical drawing for my website, illustrating a so called "client-server architecture". It should be composed of three parts:
Part 1 (front-end):
A drawing of a Smartphone and a Computer (Something that looks like a iPhone and iMac). They should be placed next to each other.
Part 2 (back-end):
A drawing of a cloud, with the words floating in it: Linux, Windows, MATLAB and C++.
The cloud should be connected to part 1 via a communication path. This is very important.
Part 3 (Algorithm):
A diagram of a so called "graphical model". See this link for how it should look:
http://www.stat.columbia.edu/~fwood/w4240/Lectures/lda_lecture.pdf
Below the graphical model, should be the first part of the last equation on page 3 (As on the attached image). Part 3 should be connected to part 2 via a weak communication path.
I need the drawing in 4 versions:
Version 1: Part 1 is highlighted, everything else is dimmed (drawn with a light grey color for instance).
Version 2: Part 2 AND the communication path between part 1 and part 2 is highlighted. everything else is dimmed.
Version 3: Part 3 is highlighted. everything else is dimmed.
Version 4: A normal drawing where everything is highlighted.
The drawing should be aligned vertical: Part 1 above part 2 abort part 3.
You are free to use any colors you like, as long as the drawing is simple and kept minimal.
