I rather enjoyed Psycho Pass. At a first glance it is set in a wonderful future in which the police leave you entirely alone because they can tell who’s guilty.

At a second glance things get dark quickly. It’s not just your intent to do something criminal but the possibility of you doing so that will get the police on your tail. The police’s guns are impressive and linked to this system – the more guilty you are, or could be, then more force the gun applies.
And they’ve made it.
Okay, they’ve not sorted out all that mind reading and psychological analysis yet. Prop makers have designed the transformation gun that opens up to reveal blue neon delights. It’s a wonder. No wonder it’s known as the Dominator in the anime.
The video demos the gun in the first minute and then, if you’re hard core, goes on to show a lecture on it in Japanese.
