How to draw OpenCL calculated pixels to the screen with OpenGL?

I wan't to do some calculated pixelart with OpenCL and display this directly on the display without CPU roundtripping. I could use interoperability of OpenCL with OpenGL and write to the texture-banks of the GPU and display the texture with OpenGL. I was wondering what would be the best way to do this, since I do not need any 3d stuff, just 2d pixelart.
