For my wallpaper i used illustrator to create objects with the pen tool and added colour Then i made them into symbols. I could then move them around more freely. I needed to arrange them into a pattern in a 300x300pixel size image. I then saved it and opened it to photo shop and then made it into a repeating pattern by using the create pattern tool.
I liked my wallpaper because i liked how just using a small umber of colours i used, black white red and yellow.
I also positioned symbols in different sizes so it gave an effect of depth to the wallpaper. having only one big image on each pattern segment i think also worked well.
I could have changed the background colour to see it worked better with another colour
