I know most of the stuff on here are games, but I wanted to share a project I have been working on for awhile. We have built a weather app on top of all the features of Cocos. Weather systems drive the particle systems and allow artist to create beautiful weather themes.
Here is a link to the app on itunes
Here is a link for android
We built a whole tool set to allow artists to build and sell there own themes. We have done some major things with the particle systems. My favorite is allowing artists to use sprite animations as a particles, and alot more.
I have a few videos of the software: video1video2
The plan is release the software to eveyone in the near future. We would love to hear from all of you. If anyone is interested let me know. Thanks!
