But there's probably some killjoy law that makes this illegal.

comes out to about $9/sq. ft., about 9 times as expensive.
But 1USD=90RUB today, and the lowest denominated note is 5RUB, coming out to 1USD=18notes. Each note is 137 mm × 61 mm, coming out to about 0.09 sq. ft. (if I'm not mistaken). Then 1USD=1.62 RUB sq. ft., so it costs
$0.62/sq. ft.
to have a green wall of ~~current~~ obsolete Russian currency.
What's surprising is that you can afford it even if you live in Russia. According to Obi and this roll of wallpaper:

> JB80201 Обои KT Exclusive Jelly Beans
> 10.05х0.53м
> 10 500 руб/рул.
the price per area isn't that different, coming out to about $2/sq. ft., meaning that if you have a clever way to paste all the single notes easily and know how not to get in any potential trouble with the law, it makes economical sense to get your wallpaper at the bank.
EDIT: according to Wikipedia, the note has been replaced by coins, and the next one is almost but not quite 10x as expensive by area.

This is a whole story about how the liquids in the bottles ‘isn’t really there’ and how it’s not a ‘real physics simulation’ - all just completely ignoring that none of this is real.
There is a sense in which the bottles in half-life Alyx are ‘fake’ - that they sort of have a magic painting on the outside of them that makes them look like they’re full of liquid and that they’re transparent. But there’s also a sense in which the bottles are real and the world outside them is fake. And another sense in which it’s all just tricks to decide what pixels should be what color 90 times a second.
Clearly, there's some sort of a physics simulation going on there, preserving the volume, some momentum, and taking gravity into account. That the result is being rendered over the shader pipeline rather than the triangle one doesn't make it any more or less "real" than the rest of the game. It's a lie only if the entire game is a lie.
