Me also. (The footprints are pink.)

I also own a second one - it's really weird. The surface is the glass is 
opaque, but when it's on you see randow colours glowing through it. (I 
imagine the glass itself is coated with some kind of phosphore - the 
colour seem to stay on one side of the globe...)

I think the contents of the globe might actually count as "plasma" too...
