How can I make an original cloud chamber?

[Gjmdp]

I'm trying to do a cloud chamber, but I think they are all too common and simple. It's just a box. I've thought about doing in a bottle, but it is just too weird, and is not original. Any other ideas or hints?

Define "original" in your criteria.

I mean, not the tipical cristal or plastic box in which you put CO2 ice and alcohol. I've thought about the design of a bottle, but that's alredy done :(
