HELLO and welcome again to Aperture Science. Since you're trapped, why not decorate the walls while you're here? These are recolors of Aikea's little 'shiftable' overlay mesh, though don't ask me how to shift them, since I have no freaking idea. BUT. Nonetheless, these are the various wall scribblings and dark stains found within Aperture's darker corners.
This shot is to show the actual detail, since it looks so small in-game. But it's still legible! Score! Though this doesn't include the mesh,
you can find it by looking here! Just download that first, plop these in second, and you too will have graffiti all over the place.
Enjoy!
