You could use GL_POINTS approach (code for cocos2d v1 here http://www.abitofcode.com/download/source/simpledrawing.zip ) and use a texture that is less of a blob and made up of dots instead. There's a few alternative textures in the example code try changing where the texture is set to see the different effects.
