Re: [PSUBS-MAILIST] Viewport design question

Plus round windows are less likely to push through. It's the same theory 
behind manhole covers, no matter which way you turn them they won't fall 
down the hole.

Although I wonder if you couldn't slope the window so that the outside 
surface had 50% more area than the inside surface and the width of the windo 
would be at a slope.... uh kind of like the attached gif shows.  this way 
the stress would be distributed over a wider area, although the corners 
would still chip after a while.

But if you want rectangular windows for asthetic purposes, could you not put 
some kind of plating to block off the bottom, top and sides so it looks 
rectangular?
