Looking for help figuring out two building techniques

[Nite01]

Hi,

I'm trying to understand a couple of building techniques used in this moc : https://www.flickr.com/photos/alexanderbing/19308416488/

1) How is the tile with red gauge pattern attached to the wall ? Behind it, there is a red brick with the masonry pattern, which I'm pretty sure cannot have a stud on the side. I thought it could be attached with a 1x1 tile with an horizontal clip on side, but it doesn't look that way.

2) How is the reversed trans-neon green cone attached to the base ? I can tell there is a bar that goes through it, and sticks to a 1x1 round plate. The problem is that if the cone was not attached in some way, the 1x1 would collapse due to gravity, but in the picture it looks at the same height as the other 1x1 round plates next to it :), Maybe there is a way to stuck the bar with some friction that I'm missing ?

Thanks :)

1) You could use thisif you wanted to attach directly to the wall.

Although in this case, it doesn't appear to be attached to the wall, but to something like .

2) It is attached to the bar, and the bar goes all the way through the floor.
