Creating Geometry Wars / GeoDefence style graphics on iPhone

I have been messing around with Cocos2d for a while but decided that, due to my lack of graphic design skills, I would be better off creating a game with Geo wars style graphics. I开发者_开发百科.e. geometric shapes etc.

Can anyone point me in the right direction on how to get started with this? I know I can create rudimentary shapes but how do I go about getting glowing shapes, particle effects etc.

Any advice or pointers in the right direction would be greatly appreciated, I have thus far been unable to find much information on creating graphics in the style that I want!

With Cocos2d the best way to get the glow would to probably be to bake them into the sprites themselves and animate between different levels of glow.

Particle effects is well covered in the programming guide, the particle designer program they mention makes it pretty painless as well
