What is the coolest fragrance packaging or marketing you've seen?

I'm personally obsessed with Wode (Paint) by Boudicca. If you haven't seen it, the fragrance came in a bottle that looked like a spraypaint can and was tinted blue with disappearing ink so when it was first sprayed it would leave a bright blue mark that would fade in the next few minutes.

I also ADORE anything by Scents of Wood, which use distinct 'human heart' shaped bottles. Super fucking goth, I love them.
