Skyspheres have ugly stich artifacts in one hemisphere.

Unless I adopt 4x4 matrices-homo coord OR quaternions the camera cannot look directly up at the sky or a cross product with global-up-vector produces a divide by zero later aka Crash.

Maybe add a manual check and set vectors by hand for now :/
