Hi Brad, I am really get impressed by this awesome library. I am developing an app which required to make some customer filter Like Alien face, squash, etc. I had looked into kGPUImagePinchDistortionFragmentShaderString code. Can you please give me any guideline for how to alter code which make Alien face effect filter? Thanks.
