All I did was create a background layer and put in a sprite with the dots you see.
Then the yin and yang symbol is just a sprite sheet animation on a background layer as well.
I meant the background on your profile. Like when I click you profile. Although since then I realized it was probably just the resolution of your monitor. I got it working and made a good background. (at least I think ) Can I ask you if my profile looks nice? Also, I freaking love your games. Like seriously how many good games can you make.
