Yes mate i have and come up just as good...
I think the glass paint was about $5 for a 250 ml container... can do heaps with that amount...
The magenta/purple coloured globes are the ones that i dipped into the glass paint...
not sure i should say this as I sell the coloured ones
but thats looks great
Yeah Mark i also have the coloured globes in my games but purple was never an option, so i made it one ! 
i am sure I have some purple .... better check .. I have been up since 5 am bloody time change
