@hingehead,
There's no way that is legitimately standing. It has to be the work of glue or a prop.
How can the very first domino on top of the base domino holding everything else up manage to stay on with the very tip? That's absolutely impossible.
Considering I see things in the background that say "this person uses paint and glue", I'd say it's glue.
Well will you look at that! Either that's left over cum residue, or that's glue on the table!
