Here are the promised paperweight pictures from my glassblowing experience. Thanks to timprov for the photography. I cut because I care, and because I haven't used the image embedding function on lj in a long time if ever and am not sure how it'll size.
Edited to add: Heh. These are showing up on my monitor larger than the paperweight actually is in real life, which is amusing, and allows me to compare features. The vein of green that looks like a crack in the bottom one is not along the surface, for example, but does run along and through the bubble. Cool.
