I'm looking for the diagram for creating one of those:
It looks really cool, however I don't know how to fold a single part. I think that it is either made from one, double-colored sheet of paper or the top, colored part is put on a white piece of paper, but I guess it'll be better if it was made from just 1 sheet of paper. I was looking for the diagram on the web, but found nothing.

I don't know the answer to your question, all I know is that it could be a model by Tomoko Fuse, since it looks similar to one of the boxes in this picture which are her models folded by herself.
Still may not be easy, but it looks simpler than a box, like a windmill base (or blinzed windmill) that has four flaps folded over "backwards" one on top of the other in sequence.
I guess if you fold the flaps in step 9 of Robin Glynn's Giftbox outwards instead of inwards it should give a similar result. I haven't tried it though.
The diagrams can be found on his homepage: http://glynnorigami.co.uk
