i have played around a lot with the stuff from this thread:
good results but totally useless - made patterns, a spaceship interior and several collages. there was one collage that i liked more than the others and really believed could be something, but it took a lot of time to put it together, with lots of experimenting, adding and removing of objects, moving stuff about, resizing, etc. i completed it today and i am just as happy with it as i thought i'd be! the subject of the collage is built on an ancient indian legend, that of the king cobra - the king of all snakes, who turns human when he is needed somewhere and in some tales built on the legend meets and marries a woman. i read one of those tales when i was a kid and both the tale itself and the illustrations of it made a huge impression on me. in that particular tale, the king cobra met a princess and turned human forever when she dared to place the royal crown on his head, thereby accepting him as her husband and regent of the country - that's the scene i've built this collage on. i'm especially happy with the slightly pre-raphaelite look of the princess, since that was the style of the original illustrations that so caught my imagination when i was little.

edit: i've worked a bit on the definition of the king cobra and i experimented a little with the princess. this is what i liked best so far:
