More experiments with DALL-E-2: Outpainting

This gives an idea of how the Outpainting tool can add a lot to the AI's initial square image. 

The original, in the center, was from my prompt asking for an underground spaceship-repair station. 
It's important to update the description in the prompt line when asking DALL-E for side images -- you want something that's related to the initial image, but different enough to be interesting.
