Yep - due to the rotating monitor I had to make some changes

Luckily the widht is nearly like the original Centipede where they had this big blue bezel between.
This was printed on a HP designjet 5000 (6 colors/600dpi) - a large format printer which can print even up to 50" width, so I ended with one sheet of paper.
For the poly, I laminated "stick-on-film" on the nacked polyboard. This is a bothsides-sticking-coating. Then I put the paper on it, laminated it all together clear, and finally made all these cutouts.
It doesn't stick that well on the polyboard though - without the glass above the edges'll peel off soon. I have greysmoked-glass too, but I'll definitely put glass over it!
To stick it directly on the glass, you could use this transofix mounting spray - of course laminating is a must, better use silk-sheen instead of high glossy. Putting it behind the glass sounds more comfortable for me though.
UPDATE Just forgot - I had to correct the colors at least on this equipment here at work so they don't look so greyish.
