A neo angled shower enclosure refers to a shower with panels that are not at right angles to each other. Usually 3 panels, the panels can be set at various degree angles depending upon the width of the panels and placement of the door. Showers of this type are commonly placed in the corner due to the possible need to re-enforce the area where the panels connect to the wall.
This is what they look like, but can be customized to fit almost any area:
