300 Reference in Portal

[UberDerpyHooves]

I have a vague memory of finding this one a while ago

If you go into the portal\materials\models\props_facemovie\wet_floor_sign folder in the Program Files, you find a certain file named wet_floor_sign.vtf. Now I think I used a program to open this and it was called "VTF Explorer" or something like that. Anyway's, when you do open it up. It shows this



Now I believe it was based off of this image here



I did a bit of research on this and it is in the GLaDOS fight at the end of the game. It is in the slideshow on the LCD monitors with the images flashing really fast above GLaDOS.

If any of you have or still have Portal, please confirm this. I don't have it anymore, but I remember the file directory by heart to lead to this interesting piece.

I currently don't have it installed, but I've seen that sign somewhere in the game before.
