Lisa Snellings, who has done amazing artwork for years (including pieces for Neil Gaiman that have inspired a number of his short stories) has a great work of art on eBay right now, that is a Victorian steampunk scene with a plasma ball, done in the Victorian style complete with framing bell jar. Well worth checking out!It is indeed. $750 at the moment but for once seemingly worth the price. But if that's still too much for you grousers, you can buy similar real working vacuum bell jars for around $120, or ornamental ones for $45. Brain and plasma not included.
