Thanks for the pics Lewis, i think that stuff is original. It's all over the inside too. I also think it is the same stuff we are seeing on screen. If you look at that link Zorg posted it even looks like it has the tread look to it from far away and when layed out it has the checkerboard pattern. Lewis' pic shows the same pattern on the bottom.
On the screen used pieces although the pattern looks treadlike from afar i think it is more jagged looking than just plain straight grooves. Here is a crappy screencap but you can see the wavy highlights. I think i may try out some of that stuff Zorg. Thanks for the headsup.
also it looks like the real stuff has a diamond pattern and that stuff has a square pattern
