Sliding Glass Panes

Sliding Glass Panes are a glass obstacle frequently encountered. They are not much of a danger when slow, but are a huge hazard when fast. They also have a counterpart which shifts instead of slides, the shifting glass panes.

The template Hostility16 used the sliding glass panes, as their taller counterpart, the Moving Glass Columns.
